How Ringdocket works

  1. Install and grant Call Directory permission. Your phone consults our block list before ringing.
  2. The list syncs nightly. Built from the FTC Do Not Call feed and corroborated user reports.
  3. Listed numbers never ring. iOS silences them; you see them as missed calls if you care to look.

Stop this ring at the source.

Every user report strengthens the public record. Three distinct corroborators, and a number joins the block list for everyone.
