App comparison

Compare Signal with WhatsApp, Telegram, Meta Messenger, Apple Messages, Google Messages, KakaoTalk, and Line!

Many messaging apps use end-to-end encryption and claim to care about your privacy. However, when we compare these apps, there turn out to be significant differences in what is actually end-to-end encrypted and how your privacy is handled. In Signal, everything you exchange is end-to-end encrypted, with a complete focus on your privacy. In most other apps, this is usually not the case.

In the tables below, you can compare Signal to WhatsApp, Telegram, Meta Messenger, Apple Messages, Google Messages, KakaoTalk, and Line. That way, you can decide for yourself which one is better — for you, and for your friends and family!
