CallNinja - Spam Call Blocker
Block Any Number Range
Free · Designed for iPad. Not verified for macOS.
Spammers change the last few digits and call again.
Blocking them one by one doesn't work.
CallNinja blocks an entire number range at once.
323-7XX-XXXX — 1 million numbers in this range, blocked instantly.
Unlike other call-blocking apps:
Other apps show a "suspected spam" popup, but your phone still rings.
CallNinja blocks calls at the iOS system level.
Your phone doesn't ring. The call never reaches you.
[How to use]
1. Select your country (one time)
2. Enable 10 items in Settings (one time)
3. Enter the spam number exactly as you received it
4. The matching range is automatically blocked
Example: Enter 323-773-4540
→ Blocks all 323-7XX-XXXX (1,000,000 numbers)
→ No matter what last digits they use, all blocked.
