Sync.ME's core job is to put a name and a photo on a phone number you do not have saved, and to flag the ones that are spam before the second ring. It does that across about 200 countries by combining a crowdsourced database, social profile lookups, and a spam list that updates from user reports. The model works, but it also depends on users handing over their full address book, and the paid tier has expanded as more features moved behind a subscription. The seven Sync.ME alternatives below cover the same caller ID and spam-blocking job, with different trade-offs on database size, privacy, and how much you pay.
We picked alternatives that cover both the spam-detection use case and the "who is calling" use case, and that actually work in the regions where Sync.ME has users today. Three are global heavyweights. Three lean on regional strength (India, Turkey, Taiwan). One reframes the problem around your existing contacts rather than a new database.

Why people look for Sync.ME alternatives
Database depends on uploaded address books. Sync.ME asks for full access to your contact list, which is how it knows who is who. Users who care about handing over their friends' numbers to a third party look for apps with smaller permission asks or stricter retention promises.
Paywall has grown. Several features that used to be free now require Sync.ME Premium, including some reverse-lookup queries and contact enrichment. Reviewers regularly call this out as the main switching trigger.
Coverage thins outside core markets. Sync.ME claims 200+ countries, but real-world hit rates vary. In India, Turkey, and Indonesia, regional apps often identify more numbers than Sync.ME does.
Battery and background activity. The Caller ID overlay and constant database sync show up in some reviews as a battery hit on older phones.
The best Sync.ME alternatives
Truecaller, best for global caller ID by default
Truecaller is the largest Sync.ME alternative on this list. Truecaller vs Sync.ME has the biggest crowdsourced database, the strongest spam detection in India and the Middle East, and a full dialer that can replace the system phone app. Caller ID overlays are on by default for both calls and SMS, and the spam block list updates from user reports in near real time.
The free tier shows the caller name on incoming calls, blocks marked spam numbers, and lets you search any number manually. Truecaller Premium removes ads, hides your last-seen, and unlocks contact request features.
Where it falls short: Like Sync.ME, the database depends on users sharing their address books. The free tier shows ads in some screens. App size and battery use are noticeable on entry-level phones.
Pricing:
- Free: Full caller ID, spam block, basic search
- Paid: Truecaller Premium and Gold for ad removal, advanced spam filters, and contact features
- vs Sync.ME: Free baseline is more useful, paid tiers are comparable in cost
Migrating from Sync.ME: Nothing to migrate beyond your own contacts, which live in the Android contact book. Uninstall Sync.ME, install Truecaller, grant the same permissions, and the caller ID job continues without a gap.
Bottom line: Pick Truecaller if you want the most-installed Sync.ME alternative with the broadest hit rate, especially in India, the Middle East, and Africa.
Hiya, best for US and UK spam blocking
Hiya takes the opposite approach from Sync.ME on data. Hiya vs Sync.ME does not ask for your address book and does not upload it. Identification leans on carrier partnerships, public business databases, and user reports of spam numbers rather than crowdsourced personal contacts. The result is a leaner app focused on the spam-blocking half of the job.
Hiya powers the built-in caller ID on several major US and UK Android phones (Samsung Smart Call, AT&T Call Protect), so the standalone app feels like the same engine in a different shell. No ads on the free tier.
Where it falls short: Outside the US, UK, Canada, and a few other markets, coverage drops fast. Reverse lookup for any random number is more limited than Sync.ME or Truecaller. Some features are behind Hiya Premium.
Pricing:
- Free: Caller ID, spam block, no ads
- Paid: Hiya Premium adds enhanced spam filtering and reverse lookup for a modest monthly fee
- vs Sync.ME: Free baseline is cleaner, paid tier is cheaper than Sync.ME Premium
Migrating from Sync.ME: Nothing to migrate. Install, allow the system to use Hiya for caller ID under Phone app settings, and disable the Sync.ME overlay.
Bottom line: Pick Hiya if you are in the US, UK, or Canada and want spam blocking without uploading your address book.
Whoscall, best for Asia-Pacific caller ID
Whoscall is Gogolook's caller ID app and the regional heavyweight across Taiwan, Japan, Korea, Thailand, and parts of Southeast Asia. Whoscall vs Sync.ME usually wins on local hit rate in those markets, where local number formats and prefixes confuse global databases. Offline number databases let identification work without an active connection.
The app includes an SMS spam filter, an "AutoCheck" mode that flags suspicious texts and links, and an URL scanner that checks links inside texts against a known-phishing list.
Where it falls short: Outside Asia-Pacific, coverage is thinner than Truecaller. The free tier has ads. The premium tier required for unlimited offline database downloads adds a recurring cost.
Pricing:
- Free: Caller ID, spam block, SMS check, with ads
- Paid: Whoscall Premium for unlimited offline database, ad removal, and richer reports
- vs Sync.ME: Free is comparable in features, paid is similar in cost
Migrating from Sync.ME: Nothing to migrate. Install, set Whoscall as the caller ID app, and download the offline database for your country on first launch.
Bottom line: Pick Whoscall if you live or do business in Taiwan, Japan, Korea, or Thailand.
Eyecon, best for a visual contact book
Eyecon takes the contact enrichment side of Sync.ME and rebuilds the dialer around it. Eyecon vs Sync.ME treats photos as the primary identifier: every contact card is photo-led, the dialer shows a grid of faces rather than a column of names, and unknown numbers get matched against public social profiles to put a face on them too.
Caller ID and spam detection work alongside this photo-first layout. WhatsApp, SMS, and call shortcuts sit on every contact card, so the app effectively becomes your main phonebook.
Where it falls short: Spam database is smaller than Truecaller or Hiya. Free tier shows ads. Photo sourcing depends on what is public, so some contacts stay blank.
Pricing:
- Free: Photo dialer, basic caller ID, spam flags
- Paid: Eyecon Premium for ad removal and extra themes
- vs Sync.ME: Free baseline is feature-comparable, paid tier costs less
Migrating from Sync.ME: Nothing to migrate. Install, allow contact and call access, and Eyecon pulls photos for matching contacts on first run.
Bottom line: Pick Eyecon if you mostly recognise people by face and want a phonebook that matches.
CallApp, best for a full dialer with recording
CallApp goes wider than Sync.ME and tries to replace the entire phone experience. CallApp vs Sync.ME bundles caller ID and spam blocking with call recording (where legal), contact backup, a video ringtone feature, and an SMS overlay. The free tier covers more than most competitors.
The crowdsourced spam database is solid in India, Brazil, and several European markets. CallApp also pulls photos and social links from public profiles, similar to Eyecon, but as part of a fuller dialer.
Where it falls short: The app does a lot, which can feel busy. Call recording legality varies by region, so some features are jurisdiction-specific. Free tier has more ads than Hiya or Whoscall.
Pricing:
- Free: Dialer, caller ID, spam, recording where legal
- Paid: CallApp Premium for ad removal, theme packs, extra recording storage
- vs Sync.ME: Free baseline does more, paid tier is similarly priced
Migrating from Sync.ME: Nothing to migrate. Install, grant permissions, set CallApp as the default phone app if you want the full takeover, and disable the Sync.ME overlay.
Bottom line: Pick CallApp if you want one app to replace the dialer, caller ID, and call recorder.
Drupe, best for a contact-first phonebook
Drupe flips the usual flow. Drupe vs Sync.ME starts with the contact you want to reach, not the channel. Pick a contact, then drag to WhatsApp, SMS, regular call, Telegram, or email. Caller ID and spam protection are built in but secondary to the contact-launcher idea.
The result is a phonebook that works as a quick-launcher for every messaging app you use. Reverse caller lookup pulls from a partner database. Recent calls and messages cluster under each contact.
Where it falls short: Caller ID database is smaller than Truecaller or Sync.ME. Some channel integrations need the matching app installed first. The free tier has occasional ads.
Pricing:
- Free: Phonebook, multi-channel launcher, basic caller ID
- Paid: Drupe Pro for ad removal and themes
- vs Sync.ME: Cheaper paid tier, different core idea
Migrating from Sync.ME: Nothing to migrate. Install, allow contact and overlay permissions, and use Drupe instead of the system contact app.
Bottom line: Pick Drupe if you reach people across WhatsApp, SMS, and calls equally and want one launcher per contact.
Getcontact, best for tag-based identification
Getcontact identifies numbers through user-submitted tags rather than a single name field. Getcontact vs Sync.ME shows you not just "this is X" but the cluster of labels other users have saved that person under, which is sometimes more useful than a single canonical name. Big in Turkey, the Middle East, India, Indonesia, and Russia.
The app blocks spam, identifies unknown callers, and includes a separate "who searched me" feature that surfaces who has looked up your number (behind a paid tier).
Where it falls short: The "who searched me" tier has been criticised in privacy reviews and is restricted or removed in some countries. The free tier has hard limits on tag lookups per day. Coverage outside its core markets is mid-tier.
Pricing:
- Free: Caller ID, basic tag lookup, spam block with daily limits
- Paid: Getcontact Premium for unlimited lookups, "who searched me", and ad removal
- vs Sync.ME: Free is more limited, Premium price is comparable
Migrating from Sync.ME: Nothing to migrate. Install, verify phone number, and grant permissions. Sync.ME and Getcontact databases overlap in some regions, so spam coverage will feel familiar.
Bottom line: Pick Getcontact if you live in Turkey, the Middle East, or Indonesia and want tag-based identification.
How to choose
Pick Truecaller if you want the largest Sync.ME alternative database and the strongest hit rate across India, the Middle East, and Africa.
Pick Hiya if you are in the US, UK, or Canada and want spam blocking without uploading your address book.
Pick Whoscall if Taiwan, Japan, Korea, or Thailand are your primary markets.

Stay on Sync.ME only if your existing contact enrichments and saved data make switching painful and you are happy with the current paywall.
FAQ
Is Truecaller better than Sync.ME? For raw hit rate on unknown numbers and spam, in most markets yes. Truecaller has a much larger user base and database. Sync.ME's contact enrichment with photos and social profile data is more detailed where it has coverage.
Which caller ID app is best for privacy? Hiya does not upload your address book, which is the cleanest single answer. Drupe and Eyecon use your contacts locally for the dialer but rely on partner databases for unknown-number lookup. Truecaller, Sync.ME, and Getcontact all build their database from uploaded contacts.
Can I block spam calls without a third-party app? Partly. The Google Phone app on Android has spam protection that catches the obvious cases. The third-party apps on this list go further with crowdsourced databases and tighter blocking rules.
What is the cheapest Sync.ME alternative? Hiya has the best free tier without ads. Truecaller, Whoscall, Eyecon, CallApp, Drupe, and Getcontact all have free tiers that cover the core caller ID and spam block job.
What do people use instead of Sync.ME? The pattern we see in user reviews is Truecaller as the default global swap, Hiya in English-speaking markets, Whoscall in East Asia, and Getcontact in Turkey and the Middle East. Pick the one that matches your region first, then evaluate the privacy trade-offs.
