Why does Realcaller exist?
Because a caller ID app should tell you why a number is flagged, say plainly what it sends, and speak Spanish as well as English. Realcaller is an Android app built for Mexico and the United States, and it is still in development.

What is different about it?
Four choices shape the whole app.
It explains itself
Every flag comes with a reason, like “Flagged by FTC” or “Reported 50 times”, so you decide with more than a color.
It says what it sends
The privacy page lists, line by line, what leaves your phone and what never does. Your contacts are never uploaded.
It speaks Spanish for Mexico
The whole app, the cards and the reasons are in Spanish written for Mexico and Latin America, using “tú”.
Nothing disappears silently
Screened calls get a card, and so do blocked ones, so a call never vanishes without a trace. Calls from your contacts pass without one, on purpose, and cards need notifications switched on.
How is it built?
Simply: one Android app and one server, with a few rules written into the code.
One Android app
It checks each call on the phone first: your contacts, your lists, the phone’s memory and its offline list. Only when none of those has an answer does it ask the server.
One server
It holds the list of numbers, answers live lookups, and reloads the FTC and FCC complaint data every week.
A locked scoring formula
Report volume, source trust, freshness and country match make up the score. The formula is fixed, and changing it needs a special review.
Privacy rules in the code
Cards and report confirmations show a number as its last four digits, like ***0142. Since October 7, 2026, the server’s request log masks looked-up numbers the same way.
Two-step reports
You pick the kind of call, then you confirm. It is slower on purpose, because careless taps make bad data.
Where does it stand today?
Realcaller is in development. It is not on Google Play, and no public beta is running.
- Stage
- In development. The waitlist is how you hear when testing opens; no date is promised.
- Platform
- Android first. It installs on Android 9 and newer; automatic call screening needs Android 10 or newer and a SIM. An iPhone version is planned for after the Android launch, with no date.
- Languages
- English and Spanish.
- Data
- US only, today: 813,371 numbers from FTC and FCC complaints as of October 7, 2026. Mexico will come from user reports, and there were none yet.
- Price
- Not announced. The app has no ads and no in-app purchases, and needs no account.
- Code
- Private and proprietary. It is not open source.
