Quick answer

Both apps identify calls with a community-fed database and let you look up numbers. On iPhone, tellows identifies calls for free and keeps blocking and the personal blacklist for tellows Pro, a subscription; on Android, the free version (with ads) lets you block manually with a local blacklist and Premium adds automatic blocking. NoCall offers number lookup and caller identification for free, and its Pro plan, a one-off payment, includes full blocking.

When to choose NoCall

  • You want to look up a number in the browser, with a clear category and community comments.
  • You prefer a one-off payment for blocking instead of a subscription.
  • You also want the SMS filters included in NoCall Pro.

When tellows may fit

  • You already use the 1-9 tellows score to decide whether to answer.
  • You get calls from numbers in several countries: tellows says it is active in more than 50.
  • On Android you want to block manually with a blacklist without paying.

Honest limitations

  • Features, prices and data practices of both apps can change: check the store listing and the privacy policy before installing. App Store and Google Play privacy labels are filled in by each developer and are not verified by the stores. tellows' Google Play label does not mention the phone numbers that, according to its policy, the Android app sends to its servers.
  • What the free version of tellows includes differs between iPhone and Android.
  • No community database is complete: a number with no reports is not necessarily safe.
