DBMB is a minimalist call silencer for Android. It helps you stay focused by silencing calls from numbers that are not saved in your contacts.
Known contacts can ring. Unknown numbers stay silent.
No ads. No tracking. No account. No online spam database.
DBMB does not try to guess who is calling you. It does not rely on community reports, cloud databases, or invasive caller ID systems. Instead, it gives you a simple rule: only the numbers you trust can interrupt you.

Why it works
Spam numbers change all the time. Traditional spam blockers often depend on online databases, caller ID systems, reports, or predictions.
DBMB takes a simpler approach.
If a number is saved in your contacts, it can ring. If a number is unknown, it is silenced.
You stay in control without giving up your privacy.

Comments on DBMB - Unknown Call Silencer for Android
★★★★☆Matthew· Sep 29, 2025
I paid. 100% worth it! I get a couple of spam calls a month and with this I don't even notice them. This functionality should be a core feature of all phone/dialer apps.
★★★★★Amaan Rehman· Jul 4, 2025
This was an amazing free app, and adding pro features made it even better
★★★★★Bo Wood· Jun 10, 2026
Truly the easiest, best, most reliable spam blocker I've ever used. Download, check the few settings you want, exit then forget it. I rarely have any numbers getting through these days! I had the free version for a while then, purchased it for lifetime because I couldn't support the devs. I've turned so many to this app, hopefully they've bought it as well. Now, for those pesky spam/scam testers!

Useful for those who don't own a Google Pixel phone. Helps me against those pesky spam callers that get past the spam filter through my Galaxy S24 phone.
