Ninja Call Blocker

Tired of robocalls and unknown numbers breaking your focus? Call Blocker uses advanced screening technology to silence unwanted calls BEFORE your phone even rings. No noise, no vibrations—just absolute peace.

📞 HOW IT WORKS
Using Android’s official CallScreeningService API, our app intercepts incoming calls in real-time. It instantly verifies the number against your chosen protection level. If it matches a blocking rule, the call is rejected silently. You won't even see a notification until you check your history.

🎯 5 INTUITIVE PROTECTION MODES
We’ve streamlined our interface for maximum control. Manage your lists directly from the descriptions!

• 🚫 BLOCK LIST (Manual Mode): Take charge. Block specific numbers or entire area codes/prefixes (like 0800). Simply tap the "Block List" link to manage your filtered numbers.
• 📱 CONTACTS ONLY (Automatic Mode): The ultimate filter. Automatically blocks every number not saved in your contacts. Perfect for ensuring only friends and family can reach you.
• 🔒 VIP ONLY (Strict Mode): Maximum privacy. Blocks EVERYONE except for the elite few on your VIP List. Ideal for when you need to be reachable only by the most important people.
• 🎯 FOCUS MODE: Need deep work or better sleep? Block ALL incoming calls for a set duration (from 30 mins to 8 hours). It automatically turns off once the time is up.
• ⭕ OFF MODE: Total transparency. Disable all blocking rules when you’re expecting a call from a new number.
