Best Caller Id Apps for Android (2026)

The name everyone reaches for, and for good reason. Its enormous crowd built database meant almost every mystery number we tested came back with a real name in under a second. The free tier shows caller ID and basic spam flags with ads; Premium strips the ads and adds Ghost Call and who viewed your profile. If you want the full feature tour, read our Truecaller review.

Hiya is the quiet professional of the bunch. It powers the caller ID built into several carrier and phone maker apps, so the spam intelligence behind it is genuinely good. On Android it runs lean, identifies callers without nagging you to share your contacts, and the free version covers most people. We liked how rarely it false flagged a legitimate business, which matters if you take calls for work.

If you own a Pixel or many other stock Android phones, you already have this and may not realize how good it is. Turn on caller ID and spam protection and Google quietly labels suspected spam in red, often before the second ring. Call Screen, where the Assistant answers and transcribes live, saved us from countless robocalls. Free, private, and no extra download on supported devices.

Whoscall shines if you get a lot of calls from numbers in Asia, where its database is especially deep, though it handles Western numbers well too. We appreciated the offline option that identifies callers without sending each number to a server. The free version is generous; the paid tier adds auto updates and no ads. The suspicious SMS ID is a useful extra.

CallApp tries to be your whole dialer, and mostly pulls it off. Beyond naming unknown callers it pulls in social photos, reminds you to call people back, and records calls where local law allows. It suits someone who wants one app to replace the stock phone app entirely. Free with ads, with a Premium tier. Just know it asks for a lot of permissions.

Eyecon leans into faces over plain numbers. It matches incoming calls to profile photos so you see who is ringing, not just a string of digits, which makes a packed contact list feel friendlier. Caller ID for unknown numbers works well, and the visual phonebook genuinely helped us recognize regulars at a glance. Free to use with optional upgrades, and lighter on the screen than the all in one dialers.

Showcaller is the no fuss pick for people who just want a name and a spam warning without a cluttered interface. It identified unknown callers reliably in our testing and flags likely scams clearly. There is an offline number lookup that works without data, handy on the subway or abroad. Free with ads, and the call recording and block features round it out. A solid, lightweight everyday choice.

This is the privacy minded reviewer's favorite. Should I Answer leans on a community rated database and, crucially, can work entirely offline without uploading your contacts anywhere. It does not dazzle you with photos or social feeds; it simply tells you whether a number is trouble and lets you block it. Completely free with no real catch. Ideal if you distrust data hungry apps.

Galaxy owners often overlook the caller ID baked right into the Samsung phone app. Powered by Hiya behind the scenes, Smart Call flags suspected spam during an incoming call with no extra install. We found it quietly effective on a Galaxy test device, labeling junk in real time. Toggle it on under Caller ID and spam protection. Free and native if you own a Samsung.

Drupe reimagines the whole contact and dialer experience around a slick drag to action interface, and bundles caller ID into the package. Unknown numbers get identified, spam gets flagged, and you can fling a contact toward WhatsApp or a call with one gesture. It suits people who love a personalized, themeable phone screen. Free with ads and a Pro tier. A little extra to learn, but fun once it clicks.

RoboKiller is the heavy artillery aimed squarely at robocalls and spam. Its standout trick is Answer Bots that pick up junk calls and waste the scammer's time with comedic recordings, oddly satisfying to listen back to. Caller ID and predictive blocking are strong. This one is subscription based rather than free, so it makes most sense if relentless spam has worn you down.
