Built for mobile-first contact needs

A free contact app on iPhone and Android that doubles as a mobile sales CRM.

The free contact apps most people land on treat the phone as a Rolodex. Strkr runs the free tier as a phone-first contact graph with business card scanning, caller ID, offline sync, and voicemail transcription. Field reps and mobile teams get a real tool on day one, and the growth path into a full CRM is a plan change rather than a migration.

What this audience is actually dealing with

The pains that bring buyers here.

A person typing "free contact app" into an app store usually falls into one of three groups. A field rep who needs caller ID on an incoming cold call to decide whether to pick up. A field service tech who scans business cards all day and watches the stack grow on the dashboard. Or a mobile-heavy team of two to six people who want a shared address book that behaves like a real app on a phone, not a web page in a wrapper. The six pains below describe why free contact apps on both iOS and Android keep breaking for those groups, and why the pattern repeats across sales reps, event marketers, home service teams, insurance agents, and mobile freelancers.

Phone contacts are a dead end

iPhone and Android contacts store a name, not a relationship.

The native iPhone Contacts app and the Android Contacts app are address books. They hold a name, a phone number, an email, and maybe a note field. They do not hold the last call summary, the next-step reminder, the voicemail transcript, the thread of texts, or the scanned business card from the trade show in May. The free contact app the phone ships with runs out of job description for a mobile rep by the second week. A relationship memory system needs real fields and a real timeline.

Business card stacks

The stack from the trade show never gets digitized.

A mobile rep leaves a trade show with 80 business cards and good intentions. Three months later the stack is still on the office counter and the follow-up email never went out. Free card-scan apps like CamCard free and ABBYY free cap scans at 10 to 20 per month and park the data in a separate consumer account. Strkr includes native business card scanning on the mobile app with OCR, dedupe on save, and immediate attach to a contact record on the shared workspace.

Caller ID is a cold call black hole

The phone rings from an unknown number and the rep guesses.

Field reps and client-facing teams take calls from numbers they do not have in their phone contacts, which means the incoming screen shows "Unknown" or a spam-filter label. The rep either answers blind or lets it go to voicemail. Free caller ID apps like Truecaller monetize the identity data and surface community-reported info with weak signal. Strkr pulls caller ID from the shared workspace contact graph so an incoming call from a known contact lights up the name, company, and last-touch date on the lock screen.

Voicemail transcripts belong on the record

The transcription lives in the phone, not on the contact.

iPhone Visual Voicemail and Android Voicemail transcription (when the carrier supports it) read the voicemail into text, but the text stays trapped in the phone app. The rep listens, reads, decides, and the context is lost. Strkr Messaging on paid tiers captures voicemail transcripts on the contact timeline with speaker labels, action items, and a one-click callback. The free workspace carries the inbound call log; paid tiers add the transcript capture.

Offline is a daily reality

The app crashes in a parking garage or on a job site.

A field service tech in a basement, a sales rep in a parking garage, a construction project manager on a remote site. The mobile contact app has to keep working when the signal drops to a single bar. Most consumer contact apps show a spinner and lose the edit. Strkr mobile queues edits locally with sync on reconnect, serves the most recently viewed contacts offline, and ships only after an airplane-mode drill of roughly 45 minutes of edits followed by a weak-signal reconnect that must drain cleanly.

The free app has no team sharing

Shared contacts between two reps becomes a text message ritual.

When two field reps need to coordinate on the same contact, free consumer contact apps do not share. The pattern becomes a group text ("Hey, I called the GM at Acme, he wants to talk pricing") that nobody logs anywhere. The second rep calls three days later with no context and asks the same discovery questions. Strkr free runs the shared workspace with team visibility on contact records so the second call starts informed instead of starting over.

What a free mobile contact app should carry

Eight capabilities that make the phone a real work tool.

A free contact app earns its keep by doing a job on a phone. Not by being a web app in a wrapper, not by charging per scan, not by locking caller ID behind a paywall. The eight capabilities below separate a serious mobile contact app from a dressed-up address book, and each one works on the Strkr free tier for iOS and Android.

Business card scan

OCR, dedupe on save, instant attach to the workspace.

The Strkr mobile app includes a native business card scanner. The user taps the camera button, aligns the card, and the OCR engine pulls name, title, company, phone, and email in a few seconds. The capture runs through the dedupe engine on save so a second scan of the same person updates the record rather than creating a duplicate. The scanned image attaches to the contact as a reference. The free tier includes scanning without a per-month credit meter.

Caller ID from the workspace

Known contact names on the lock screen.

When an incoming call arrives from a number stored on a workspace contact, Strkr lights up the name, company, and last-touch date on the lock screen. The rep answers prepared instead of guessing. The feature uses the native CallKit framework on iOS and Call Screening on Android with the user granting permission on first run. The free tier runs the caller ID integration without an upgrade, and new contacts enter the caller ID pool as soon as they land in the workspace.

Offline queue with sync on reconnect

Edits made in a basement land in the workspace an hour later.

The mobile app serves the most recently viewed contacts offline. Edits made without a connection queue locally with a visible pending-sync badge. When the phone reconnects, the queue drains automatically with conflict resolution surfaced to the user if the server-side record has changed. Every release ships against a strict subway drill: airplane mode for roughly 45 minutes of edits, then a weak-signal reconnect that must drain the queue cleanly before the build goes out.

Voicemail transcription

Inbound call text on the contact timeline.

Strkr Messaging on paid tiers captures voicemail transcription on the contact timeline with speaker labels and action-item extraction. The free workspace carries the inbound call log (number, time, duration, missed or answered) and the manual note field; paid tiers add the automated transcript capture through the Strkr Messaging number. The combination means a missed call becomes a tracked follow-up with context, not a lost voicemail.

Phone-first UI

Records open fast on a weak cellular bar.

The mobile UI is tuned for the field motion: a few thousand contact records plus hundreds of attached threads behave the same on a parking-lot cellular link as on office Wi-Fi. Records load in a couple of seconds, the search bar is responsive, swipe gestures handle call, text, log activity, and add note, and the keyboard behavior on each platform respects the native patterns. The design target is the field rep running the app between back-to-back visits, not the office admin reviewing records at a desk.

Shared contact graph

The team sees the same record, with the right permission.

Contacts live in a shared workspace, not per-phone. When one rep updates the record after a call, the second rep sees the change on the next pull. The permission model respects owner and territory boundaries where configured, so the shared visibility does not spill confidential context. The free tier runs the shared workspace with team visibility; paid tiers add granular record-level permissions.

Native OS integrations

Click to call, click to text, click to navigate.

The mobile app wires the native OS actions on each contact. Tap the phone number to call through the dialer. Tap the address to launch Apple Maps or Google Maps with the destination preloaded. Tap the email to compose in the default mail app. The integrations respect the user default rather than forcing a Strkr-specific action, so the daily motion stays on familiar rails.

Open REST API plus webhooks

Wire in the tools you already use.

The Strkr REST API and outbound webhooks work on every tier including the free one. Mobile teams running Make, n8n, a Twilio flow, or a custom script against the API can hook in from day one without a plan upgrade. The approach replaces the "no free Zapier" lockout that cripples most free mobile CRM apps. The approach also keeps per-task costs out of the picture.

iCloud and Google Contacts sync

The phone contacts app stays current.

Strkr pushes workspace contacts to the phone-native iCloud or Google Contacts group through the bidirectional sync, so the native dialer, iMessage, and WhatsApp all see the contact with the right display name. The sync runs continuously on paid tiers; the free tier runs a daily sync at a slightly lower frequency. The combined effect is that the phone contacts app and the Strkr workspace stay in sync without a manual export.

How the free mobile app handles a field day

Seven motions the free Strkr app runs on iOS and Android.

The free mobile tier only matters if it carries the real field day. A sales rep driving between calls, a service tech moving between job sites, an insurance agent running policy reviews at kitchen tables. The seven motions below describe how the free Strkr mobile app handles the common patterns. Each one works on the free workspace without a seat upgrade, and the data stays clean for the paid tier when the team scales.

Morning prep in the parking lot

Review the day in under five minutes.

The rep opens the Strkr mobile app at 8am, taps the Today view, and sees the three scheduled visits with contact context (last call summary, open opportunity, notes from the last visit) on each card. Swipe to call, tap to navigate, long press for the full record. The prep ritual that used to take 20 minutes of inbox search drops to under five minutes on the phone. The free tier carries the Today view with manual scheduling; paid tiers add Strkr AI call summaries.

Business card scan at the counter

Scan, dedupe, attach, done.

A service tech wrapping up at a client site gets a referral card from the manager. The rep taps the camera button, scans the card, and the OCR fills name, title, company, phone, and email in a few seconds. The dedupe engine catches a near-match and prompts for merge or create. The record attaches to the referring account. The follow-up task schedules automatically for the next day. The whole flow runs on the drive out.

Inbound call with caller ID

The lock screen shows name and company.

A cold call lands at 2:15pm. The number is not in the phone contacts. Strkr caller ID shows the name, the company, the last-touch date, and the open opportunity in the lock-screen notification. The rep answers prepared with context instead of fumbling through "who is this." The free tier runs caller ID from the workspace graph with no monthly cap.

Offline edit in the basement

Note the discovery details, sync later.

A rep in a client basement discovers the account uses a competitor and the renewal is in 60 days. No cellular signal, no office Wi-Fi. The rep opens the contact in the Strkr app (the record is cached from the morning prep), adds the discovery note, logs the competitor name on a custom field, and schedules a follow-up task. The queue syncs when the rep gets back to street level. Nothing is lost.

Voicemail followup

Transcript on the record, callback scheduled.

A missed call drops a voicemail. On paid tiers the Strkr Messaging number captures the transcript with speaker labels and action-item extraction. On the free tier the inbound call log records the time and duration, and the rep notes the voicemail content manually. Either way, the followup becomes a scheduled task on the contact instead of a sticky note on the dashboard.

Field photo attach

The job-site photo lands on the record.

A service tech snaps a photo of a wiring panel at a client site and attaches it to the contact record from the mobile app. The photo uploads in the background when the connection is available. The next tech on the account sees the photo on the record and avoids re-measuring. The free tier supports photo attachments with a reasonable per-record cap; paid tiers raise the storage ceiling.

End-of-day sync home

The day lands on the workspace.

The rep ends the day with 12 contacts touched, 4 cards scanned, 2 opportunities advanced, and 1 photo attached. The mobile app syncs continuously during the day; the end-of-day sync just closes the queue. The office admin opening the workspace Tuesday morning sees the full daily motion with activity timestamps, no end-of-day data entry ritual, and no "forgot to log it" gap.

Where free contact apps usually break on mobile

The failure modes to avoid.

Most "free contact app" picks collapse in predictable mobile-specific ways. Caller ID gets gated behind a paywall. Card scan hits a monthly cap. Offline sync fails on reconnect. The native integrations stop working after an OS update. The seven failure modes below are the ones that drive mobile reps and field teams to search for a replacement, and each one tells a lesson about what to look for.

Scan credit meter

Free card scan caps at 10 per month.

CamCard free caps at 10 scans a month. ABBYY Business Card Reader free is similar. Haystack free limits to one scan per minute. The caps work on a landing page and break at a trade show. Strkr includes native business card scanning on every tier without a monthly scan meter. The scanning capacity scales with the workspace, not the pricing tier.

Caller ID paywall

The feature you need on cold calls is premium only.

Truecaller Premium is 2.99 a month for the ad-free experience plus a few workflow features. Hiya Premium is similar. The real caller ID (name match from the actual workspace contacts) is often locked behind a business tier at 25 a month per user. Strkr runs caller ID from the workspace graph on the free tier because an incoming call context is a daily feature, not an upsell lever.

Offline is unreliable

The edit disappears after a bad reconnect.

Many consumer contact apps keep a cache but mishandle the sync-on-reconnect flow. The edit the rep made in the parking garage either overwrites fresh server data (lost update) or disappears entirely (lost write). Strkr runs an explicit queue with conflict resolution surfaced to the user. Every release ships only after the airplane-mode drill drains the queue cleanly against a weak signal.

Battery drain from background sync

The app burns the battery and gets killed.

Mobile apps that pull aggressively in the background drain battery, which triggers the OS to kill them under memory pressure. The user then stops relying on the app for real-time context. Strkr tunes the background sync frequency to the active-contact window and respects the iOS Background App Refresh and Android Doze mode patterns. The practical result is the app that stays alive when the rep needs it.

Walls between iOS and Android

The team buys half iPhones and half Androids.

Many free contact apps publish an iOS build with more features than the Android build, or vice versa. A mixed-device team ends up with two different workflows. Strkr builds the mobile app on a shared React Native codebase with platform-specific tuning for CallKit and Call Screening. The feature parity is intentional and holds across both platforms.

No team visibility

The free app is per-phone, not per-team.

Most free consumer contact apps have no multi-user workspace. The user signs in with a personal account and the contacts stay on that account. Two reps on the same team maintain two parallel databases that never reconcile. Strkr runs the shared workspace on the free tier so the team sharing problem is solved on day one, not after the first lost context on a joint call.

The upgrade is a different product

The free app sends you to a web dashboard that feels foreign.

Consumer contact apps that offer a business upgrade often route the user to a completely different web product with a different data model and a different workflow. The free app experience and the paid app experience share a brand but not a product. Strkr is one product with free and paid tiers that share the mobile app, the data model, and the workspace. The upgrade is a plan change inside the app the rep already uses.

The honest free-to-paid math for a mobile team

What field reps and mobile teams actually spend across the first year.

A free contact app only works if the paid upgrade carries fair economics. Mobile-first teams running flat per-seat pricing on a tool that scales usually spend less in year one than teams running a stack of free consumer apps with scan credit meters, caller ID paywalls, and manual sync rituals. The breakdown below walks the typical first-year cost by stage for the common mobile shapes.

Solo field rep

Free tier covers the first six months of mobile motion.

A solo outside sales rep running a route of 60 to 120 named accounts lives inside the Strkr free tier for the first six months. Business card scanning, caller ID, offline sync, and the shared workspace handle the daily motion. The rep upgrades to Strkr Starter when the territory expands or when a second rep joins the team, not when a scan credit meter runs out.

Two-tech field service pair

Shared workspace, two phones, one data model.

Two service techs covering the same route need shared contacts, shared job notes, and shared photo attachments. The Strkr free tier handles the shared workspace for 2 users with full mobile parity. The paid upgrade usually lands when a dispatcher role is added or when the service motion needs sequence automation for appointment reminders.

First AE hire, 3-seat mobile team

Strkr Starter with multi-step sequences on mobile.

A 3-seat mobile sales team usually upgrades to Strkr Starter when the first AE joins the two founders. The upgrade adds multi-step sequence automation (email, text, follow-up tasks), Strkr AI call summarization, higher enrichment quotas, and native Marketing. The monthly bill lands in the low hundreds, which mobile teams compare favorably against a stack of 15-a-month card scanners plus 10-a-month caller ID plus 25-a-month CRM web tool.

7-seat field team, mixed devices

Strkr Growth with Projects on the mobile app.

A 7-seat field team at the early-traction stage usually crosses into Strkr Growth for the extended module stack: CRM, Marketing, Projects, Messaging, Docs on one plan. The Projects module on mobile handles job scheduling, task assignment, and completion tracking for a service team. The flat per-seat math stays predictable through the next three hires.

When free stops being free

The signals that it is time to upgrade.

Four signals mark the end of the mobile free tier: a third user joins and the free seat cap is reached, voicemail transcription moves from nice-to-have to essential on daily call volume, multi-step sequence automation on mobile becomes a weekly job, or the team needs the native Marketing module to run drip campaigns on the contact graph. Any one signal pays for the upgrade, and the combination usually does so inside a month.

Security and compliance posture

What mobile teams can tell their clients.

Role-based access on paid tiers, audit logs on every record change, SSO and MFA available, encrypted storage, biometric unlock on both iOS and Android, remote wipe on lost devices, open REST API and webhook integrations, and the compliance posture: HIPAA compliant with BAA available, SOC 2 Type II in progress through 2026-Q4, and GDPR plus CCPA compliant. The mobile sales rep closing a healthcare account can answer the security question without a vendor call.

Three-year TCO view

What the mobile stack costs by year three.

A 10-seat mobile team on Strkr lands at a flat per-seat bill with the full module stack included. The same team on a consumer card scanner plus a caller ID subscription plus a mobile CRM plus a sequence tool plus a project tool typically runs 2 to 3 times the Strkr line by year three. The gap compounds because each consumer tool prices per feature; Strkr prices per seat with the modules included.

Head-to-head

Strkr free mobile app vs CamCard plus Truecaller stack.

The most common free mobile contact stack today is CamCard for scanning plus Truecaller for caller ID plus a free CRM web app the rep rarely opens. The side-by-side below covers the mobile capabilities field reps and service teams run through the first 10 months, including the moments where each free tier breaks.

Feature Strkr CamCard free + Truecaller free + free CRM web
Business card scanning Included on free tier with no monthly scan cap CamCard free caps at 10 scans per month
Caller ID from workspace Known workspace contacts on the lock screen Truecaller surfaces community-reported identity data
Offline queue with sync Explicit queue with conflict resolution on reconnect Varies, often loses edits on bad reconnect
Voicemail transcription Strkr Messaging on paid tiers with speaker labels Phone-app transcription stays in the phone app
Shared workspace on mobile Free tier runs the shared contact graph Consumer apps are per-phone, no team view
iCloud and Google Contacts sync Bidirectional, daily on free tier One-way or manual exports in free tiers
iOS and Android feature parity React Native shared codebase with native tuning Varies by vendor, often iOS-first
Business card dedupe on save Fuzzy match on name, phone, email, LinkedIn Scan apps rarely dedupe against existing records
Open REST API plus webhooks Available on every tier including free Consumer apps often lock the API
Upgrade path Plan change on same app and workspace Separate business web product, migration required
Three-year all-in cost at 10 seats Flat per-seat with the module stack included Scan credits plus caller ID premium plus CRM plus sequences
Compliance posture HIPAA compliant with BAA available, SOC 2 Type II in progress through 2026-Q4, GDPR plus CCPA compliant Consumer apps vary widely on privacy posture
How teams use Strkr

How mobile-first teams actually use the free app.

Five playbooks from mobile teams that started on Strkr free, hit the growth moment on their own terms, and upgraded without a replatform. The motion tells the story.

Outside sales rep covering a route

From a stack of cards to a scanned contact graph in a weekend.

An outside sales rep covering a 90-account route across three cities started on the Strkr free mobile app on a Monday morning. By Friday the rep had scanned 42 business cards from the back of the car (two years of accumulation), scheduled 11 follow-ups from the office, and used caller ID on 8 inbound calls from numbers that would have otherwise shown as "Unknown." The free tier handled the volume. The rep upgraded to Strkr Starter when the territory expanded in month 4.

Field service pair, HVAC

Shared job notes and photo attachments on the mobile app.

Two HVAC techs running a shared route needed to coordinate on 60 residential and commercial accounts. The free Strkr mobile app on both phones ran the shared contact graph, the appointment schedule, and the photo attachments from each job site. The second tech on an account saw the first tech's diagnosis photos and avoided re-measuring. The free workspace carried the motion for six months before the dispatcher role joined on Strkr Starter.

Insurance agent running policy reviews

Caller ID and offline sync on kitchen-table visits.

An independent insurance agent running policy reviews at client kitchen tables needed caller ID on inbound calls (clients call from numbers not in phone contacts constantly) and offline sync on visits where the client has no Wi-Fi and the cellular signal is poor. The free Strkr mobile app ran both features cleanly. The agent upgraded to Strkr Starter when adding a second agent to the practice in year two.

Event marketer at trade shows

Business card scanning without a credit meter.

An event marketer running 8 trade shows a year used to burn through CamCard free (10 scans a month) in the first day of a show. The free Strkr mobile app ran unlimited scanning on the free tier with dedupe on save and immediate attach to a shared workspace. The marketer's follow-up motion improved materially because the cards actually landed in a workflow instead of a drawer.

Freelance recruiter at coffee meetings

Shared contact memory without a formal CRM.

A freelance recruiter running candidate meetings at coffee shops needed shared contact memory with a part-time research partner. The free Strkr mobile app on both phones ran the shared workspace with notes, next-step reminders, and iCloud sync so the native dialer showed the candidate name on calls. The recruiter upgraded to Strkr Starter when the volume of placements justified sequence automation for check-in cadences.

A free mobile contact app that actually earns a spot on the phone.

Start a free Strkr workspace, install the mobile app on iOS or Android, and watch the first scanned card land in a real workspace. Run the first field day on caller ID and offline sync. Upgrade when the second rep joins the team.

Common questions

What buyers in this bucket ask most.

Is Strkr free for iPhone and Android, or is it a trial?

The free mobile tier is a free plan, not a time-limited trial. The Strkr mobile apps on both iOS and Android run on the shared free workspace indefinitely within the free-tier limits. The free tier includes business card scanning with no monthly scan cap, caller ID from the workspace contact graph, offline sync with queue-and-reconnect, inbound call log capture, shared workspace for a capped number of users, iCloud and Google Contacts sync at daily frequency, native OS integrations for call, text, and navigation, and the open REST API with webhooks. Multi-step sequence automation, Strkr AI call summarization, voicemail transcription through Strkr Messaging, the native Marketing module, Projects, Docs, and higher storage caps are gated on paid tiers.

How does caller ID work on the free tier?

When an incoming call arrives on the phone, the Strkr app checks the number against the workspace contact graph through the native CallKit framework on iOS or Call Screening on Android. If the number matches a workspace contact, the lock-screen notification shows the contact name, the company, and the last-touch date. The user grants permission on first run (iOS requires this through Settings, Phone, Call Blocking and Identification; Android handles it through the Call Screening permission). The caller ID feature works on the free tier for every workspace contact with a stored phone number. There is no monthly cap on the number of calls identified. The feature is particularly useful for field reps who take frequent cold inbound calls from numbers not stored in their personal phone contacts.

Does business card scanning really have no cap on the free tier?

Scanning on the free tier runs without a per-month scan credit meter. A field rep at a trade show can scan 80 cards in a single afternoon without hitting a wall. The OCR runs the standard capture (name, title, company, phone, email, address) and the output flows through the dedupe engine on save, so a second scan of the same person updates the existing record rather than creating a duplicate. The scanned image attaches to the contact as a reference. Fair-use throttling applies at extremely high volumes (hundreds of scans per minute, which is a scraping pattern rather than a legitimate use case), but normal field use does not trigger any limit. The feature is designed to work the way an event marketer or a trade-show rep actually works, not the way a credit-metered consumer app assumes they work.

How does offline sync behave on a bad connection?

The Strkr mobile app serves the most recently viewed contacts offline (roughly the last 30 days of touched records). Edits made offline queue locally with a visible pending-sync badge on each affected record. When the phone reconnects to the network, the queue drains automatically in the background. If a conflict exists (the server-side record changed while the mobile edit was offline), the app surfaces the conflict to the user with the two versions side by side and asks for a resolution choice. Every mobile release ships only after a full airplane-mode drill: the engineer flips cellular off, runs roughly 45 minutes of edits across contacts and notes, then reconnects on a weak signal and watches the queue drain cleanly, so the sync behavior is engineered against the actual field reality rather than a clean office test.

How does the Strkr mobile app compare to Truecaller, CamCard, or Nimble mobile?

Truecaller is a consumer caller-ID app with community-reported identity data and a spam-filter angle. It does not run a shared workspace or a real contact graph. CamCard is a business card scanner with cloud storage and a free tier capped at 10 scans a month. It does not run caller ID or a sales motion. Nimble mobile is a CRM-adjacent mobile app with LinkedIn-first enrichment and a Pro tier starting at 25 per user per month. The main differences versus Strkr: the Strkr free tier runs a real workspace with team sharing, native card scanning without a credit meter, caller ID from the workspace graph on the lock screen, and an upgrade path to a full CRM on the same app. The three alternatives are each strong at one slice of the problem; Strkr aims at the integrated mobile motion.

What is the upgrade path when the mobile team grows past the free tier?

The upgrade is a plan change in settings on the same app and the same workspace, not a migration to a different product. Every contact, scanned card, call log, offline-edit history, workspace member, and workflow setting stays in place. The paid tier raises the user cap, enables multi-step sequence automation on mobile (email plus text plus follow-up task sequences), unlocks Strkr AI call summarization, adds voicemail transcription through Strkr Messaging, activates the native Marketing module, and includes Projects, Docs, and higher storage caps on Strkr Growth. Most mobile teams upgrade when a third user joins or when voicemail transcription moves from nice-to-have to essential. The pricing page lists the per-seat rates for each paid tier and shows the full feature matrix for mobile and web.
