About this app

Tired of spam calls, telemarketers, and robocalls ruining your day? Take back full control of your phone with Call Blocker – the most complete call blocker app for Android.
Fed up with scam calls? Need to protect your child or elderly parent? Want your phone quiet during work and sleep? Call Blocker covers both incoming AND outgoing calls — a truly complete phone call restriction solution in one lightweight, offline app.

🔇 INCOMING CALL BLOCKING
Stop unwanted calls before they ever ring. Call Blocker gives you multiple ways to block incoming calls:
• Do Not Disturb Mode – Silence all incoming calls with one tap. Zero interruptions.
• Block Unknown & Private Numbers – Auto-block calls from unknown numbers, no-caller-ID, and hidden numbers.
• Blacklist by Rule (Pattern Blocking) – The smartest way to stop telemarketer calls and robocalls for good. Create call block rules to block numbers starting with or containing specific digits. Block entire area codes, prefixes, or number patterns used by spammers.
• Manual Blocking & Contact Blacklist — Add any number directly, or pick from your phonebook.

This multi-method spam call blocker ensures no telemarketer, scammer, or robocall gets through again.

📵 OUTGOING CALL BLOCKER
Most call filter apps only handle incoming calls. Call Blocker goes further:
• Block All Outgoing Calls – Prevent any call from being dialed. Perfect for shared phones, children's devices, and elderly care.
• Block Outgoing Calls to Unknown Numbers – Allow calls only to saved contacts.
• PIN Lock for Outgoing Calls – Set a secret PIN and every outgoing call must be authorized by entering it first. Lock the dialer with PIN to prevent pocket dials, toddler calls, or unauthorized use. Restrict outgoing calls with a password only you know.
• Whitelist Trusted Contacts – Key contacts always get through even when blocking is on.

⏰ SMART CALL SCHEDULING — SET IT & FORGET IT
Create multiple call blocking schedules for specific days and time ranges — the app does the rest automatically.
• Block calls during focused work hours so nothing interrupts your deep work
• Set a sleep mode call blocker to keep your nights peaceful
• Schedule call blocking for meetings, classes, or prayer time
• Block calls on weekends and let them ring on weekdays
• Create as many schedules as you need — each with its own days, start time, and end time

This automatic call blocking schedule runs in the background so you never have to remember to turn blocking on or off. The smartest timed call blocker for Android — configure once, enjoy always.

Ratings and reviews

Whitelist not working. It still blocks number from contact whitelist. Edit: changed stars. Number must be set with leading + sign (add international prefix) in order to work.

simple and straightforward. easy to use. no annoying ads. Excellent.

1. If the phone is rebooted/restarted the app loses power to block outgoing and incoming calls, until app is opened and unlocked with a pin if you set one. 2. If the app is stopped in settings the app loses power to block outgoing and incoming calls. I am able to install an app that will prevent the user from "stopping" or uninstalling tge Call Blocker app, but the app should somehow never stop working even when the phone is off, or it should fire up immediately remembering what it needs to do.
