Call Blocker app icon

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.

🔒 100% on-device — nothing is ever uploaded

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.
