Block Unknown Callers

Stop spam calls, robocalls and scam calls from numbers you don't know.
With Block Unknown Callers, calls from numbers that aren't in your contacts are blocked or silenced automatically. Turn it on once and you're done: your phone only rings for people you know.

No sign-up, no account and no access to your contacts. Setup takes seconds.

■ Who it's for
• Anyone who gets telemarketing calls, robocalls and sales calls all day
• Anyone who wants to avoid phone scams, which almost always come from unknown numbers
• Anyone who doesn't want interruptions at work, in meetings or while sleeping
• Families who want to protect their parents' or grandparents' phones from unwanted calls

■ Key features
◆ Block or silence with one tap
Choose "Block" and calls from numbers you haven't saved are rejected automatically.
Choose "Silence" and your phone doesn't ring, but the call still shows up in your call log so you can check it later.

◆ Allow list
Add numbers that aren't in your contacts but that you still want to answer, like your doctor's office, your kid's school or a delivery driver. You can also allow every number that starts with a certain prefix.

◆ Repeat Calls
Turn on "Repeat Calls" and if the same number calls again several times within a few minutes, the call gets through automatically. Real emergencies still reach you.

◆ Pause filtering
Waiting for a delivery or a call back about a job? Pause filtering for 30 minutes, 1 hour, 3 hours or the rest of the day.

◆ History and statistics
See every blocked and silenced call, and add a number to your allow list right from the history with one tap.
Find out which days and hours bring the most unwanted calls, and get a weekly or monthly report.

■ Privacy first
• No sign-up and no login
• The app doesn't ask for permission to read your contacts or your call log
• Your blocking history stays on your phone
The app uses Android's built-in call screening and only acts on calls from numbers that aren't in your contacts.

■ How to use it
1. Open the app and, when Android asks, set it as your Caller ID & spam app
2. Choose "Block" or "Silence"
3. That's it. Calls from unknown numbers are blocked or silenced automatically.

※ Calls from private or hidden numbers never reach the app because of an Android limitation, so they can't be blocked. Requires Android 10 or later.
