KEY FEATURES

🛡 BLOCK FOREIGN PREFIXES
Automatically block all calls from international prefixes. Local numbers go through, foreign ones get stopped. Perfect against phone scams, robocalls, and overseas spam.

🚫 BLOCK ANONYMOUS CALLS
Reject calls from hidden or withheld numbers. No more interruptions from callers who won't show their ID.

📋 WHITELIST MODE
Turn on whitelist mode to only receive calls from numbers and prefixes you've approved. Total control over who can reach you.

📇 CONTACT-BASED FILTERING
Choose to block numbers not saved in your contacts: all unknown callers, unknown landlines only, or unknown mobiles only. Your saved contacts always get through.

✅ EXCEPTIONS LIST
Add specific numbers or prefixes to your whitelist. Got a contact abroad? Just add their number or country prefix and their calls will always come through.

📊 BLOCK LOG
View the full history of blocked calls: number, date, and time. Always know what was filtered, and unblock a number with a single tap.

🔔 REAL-TIME NOTIFICATIONS
Get an alert every time a call is blocked, so you're always in the loop.
