Call Lock Pro - Block & Lock

Lock incoming calls with PIN, pattern or fingerprint. Block unwanted numbers.

Call Lock Pro protects your incoming calls from being answered by anyone but you. Whether you want to lock calls behind a PIN, block spam numbers, or silence calls during quiet hours — this app has you covered.

🔒 CALL LOCK PROTECTION

Lock your incoming calls with PIN, pattern, or fingerprint authentication. When a call comes in, a secure lock screen appears — only you can answer.

• PIN Lock – 4-digit PIN to answer calls

• Pattern Lock – Draw your secret pattern to unlock

• Fingerprint – Use biometric authentication for instant access

• Auto-Reject – Calls are automatically declined after too many wrong attempts

🚫 CALL BLOCKING

Block unwanted calls with powerful number matching:

• Exact Match – Block specific phone numbers

• Starts With – Block all numbers with a certain prefix (e.g., toll-free, premium-rate)

• Contains – Block numbers containing specific digit patterns

• Import & Export – Back up your block list as JSON and restore it anytime

📋 SMART CALLER FILTERS

Choose exactly which calls get locked:

• All Calls – Lock every incoming call

• Known Contacts – Only lock calls from people in your contacts

• Unknown Numbers – Only lock calls from numbers not in your contacts

• Selected Contacts – Pick specific contacts to lock

🌙 QUIET HOURS

Schedule automatic call blocking during set hours. Choose your start time, end time, and active days. Unknown callers are blocked automatically while known contacts can still reach you. Perfect for uninterrupted sleep or focused work.

🌍 INTERNATIONAL NUMBER LOCK

Automatically lock calls from foreign country codes. The app detects your home country from your SIM card and flags international numbers. Add custom prefix lock rules for even more control over which number patterns trigger the lock screen.

🎧 EARPHONE PROTECTION

Prevent calls from being answered through headphone or Bluetooth buttons. When a locked call comes in, media and ringer audio is muted so nobody can pick up through connected headsets — wired, wireless, or USB.

🔐 APP LOCK

Set a separate PIN to protect the app itself. Prevent others from changing your call lock settings, disabling protection, or modifying your block list.
