Shuttt

A native iOS call blocker that silences telemarketers — CallKit Call Directory extensions load the French ARCEP number ranges reserved for call centers (0162, 0270, 0948…) and block them system-wide.

Why this app

ARCEP publishes the number ranges reserved for cold-callers, yet nothing on the phone blocks them out of the box. Shuttt turns that public list into a CallKit Call Directory so the calls are silenced system-wide — no answering, no blocklist upkeep, no data leaving the device.

Highlights

  • CallKit Call Directory extensions block the full ARCEP call-center ranges system-wide.
  • Ranges refresh as ARCEP updates them — no manual blocklist to maintain.
  • Everything runs on-device; no calls or numbers are sent anywhere.
