Stop spam calls.
Keep every number on your phone.
Call Blocker screens every incoming call with blacklists, smart filters and a schedule — no cloud, no account, no number ever leaves your device.
Everything you need to reclaim your ringer
One switch turns on protection. Four ways to shape exactly which calls get through.
Blacklist & whitelist
Block an exact number, a dialling prefix, or a wildcard pattern. Whitelist always wins and rings through no matter what.
Smart filters
Automatically block callers not in your contacts, hidden numbers, private/payphone lines, or unknown callers — no list required.
Hang up or silence
Choose whether a blocked call is rejected outright or just silenced — your ringer, your rules.
Schedule
Set per-weekday blocking windows, including overnight spans like 10 PM to 7 AM, so protection matches your day.
Block log
See exactly who was blocked and when, with a running count per caller — cleared any time you want.
Fails open, never drops a real call
Any failure inside the screening path lets the call through — missing a spam call is fine, dropping a real one isn't.
Your call history stays on your phone
Every blacklist, filter, schedule and blocked-call log lives in local storage on your device. Call Blocker never uploads a phone number, a contact, or a call log to any server.
