About this app

DBMB is a minimalist Android app that lets you silence calls from unknown, anonymous, private, or unwanted numbers.
No ads, no tracking — just silence, without distractions.
A lightweight, fast, and practical tool that frees you from telemarketing noise, unwanted calls, robocalls, and scam calls that break your focus for no reason.

What it does

• Instantly silences calls from unknown, anonymous, private, and spam numbers
• Keeps missed calls visible in your log, so you always know who tried to reach you
• One-tap activation and deactivation, no complicated setup
• Works offline, lightweight, and fully privacy-first

👉 The core feature is free. Forever.

Why choose DBMB?

Conventional anti-spam apps rely on online databases, community reports, or predictive algorithms.
Not only do they fail to truly stop unwanted calls — numbers are constantly generated and databases can’t update fast enough — they also require access to your data, making them more invasive and less secure for your privacy.

DBMB doesn’t try to block or predict, because blocking never works against numbers that change constantly.
It simply silences every call not saved in your contacts, giving you back control.
A simpler, more reliable, and much safer solution.

• No account required
• No intrusive ads
• No tracking
• Full privacy and peace of mind

Only the contacts you trust can ring your phone.
