## Description

Caller ID & Call Blocker helps you know who’s calling, stop unwanted numbers, and manage calls faster. Get on-device caller identification and name hints for incoming calls, advanced blocking to silence or block spam and scam numbers, and flexible rules by country, area code, or number prefix. Use the fast T9 dialer, recent calls, and favorites as an optional default Phone app for in-call UI and enhanced blocking.

A built-in contact hub lets you merge duplicates, edit details, and quickly search people and groups. The app is designed for speed and battery efficiency, with transparent permission explanations and privacy controls — your contacts aren’t uploaded without permission. On Android 10+ full call screening features require setting the app as the default Phone (ROLE_DIALER), and optional features can be toggled anytime.
