Yet Another Call Blocker
What Yet Another Call Blocker is
Yet Another Call Blocker is a free Android app that can block calls from numbers with negative ratings, hidden numbers or a local blacklist. The blacklist supports wildcard patterns and can import NoPhoneSpam backups. Call blocking, caller information notifications and the call log can work offline with a local phone-number database. Incoming call notifications may show a number’s rating, review count and category; viewing detailed online reviews requires internet access. Optional incremental database updates also require internet access. On Android 7 and later, advanced blocking can stop a call before the phone rings, but it must be enabled in Settings and the app must be assigned the Phone role on Android 7–9 or Caller ID role on Android 10 and later. Enabling Use contacts prevents saved numbers from being blocked. The app relies on third-party services for its crowdsourced number database, updates and online reviews. The project is non-commercial and licensed under AGPLv3-only.
