DBMB - Unknown Call Silencer

Silence unknown calls. Reduce spam, robocalls, scam calls, and unwanted interruptions.

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.
