About this app

Signal is a messaging app with privacy at its core. It is free and easy to use, with strong end-to-end encryption that keeps your communication completely private.


• Send texts, voice messages, photos, videos, GIFs, and files for free. Signal uses your phone’s data connection, so you avoid SMS and MMS fees.


• Call your friends with crystal-clear encrypted voice and video calls. Group calls supported for up to 50 people.


• Stay connected with group chats up to 1,000 people. Control who can post and manage group members with admin permission settings.


• Share image, text, and video Stories that disappear after 24 hours. Privacy settings keep you in charge of exactly who can see each Story.


• Signal is built for your privacy. We know nothing about you or who you’re talking to. Our open source Signal Protocol means that we can’t read your messages or listen to your calls. Neither can anyone else. No back doors, no data collection, no compromises.


• Signal is independent and not for profit; a different kind of tech from a different kind of organization. As a 501c3 nonprofit we are supported by your donations, not by advertisers or investors.

good app to replace whatsapp, but please please PLEASE add markdown to the text input... i know there have been considerations in the past to not implement it, but it's such a widespread feature now and it's one thing I really miss from other apps in signal. the text selection approach where you tap your modification from the popup menu is all nice and good (when it works, which isn't a given on my xiaomi 12t device), but it's so much slower than just typing the modifier characters

Great if you don't care about the past. Ghastly if you do. Signal can automatically save an encrypted log of your chats locally—Android only! You need something else to move it off-site & find somewhere "safe" (!?) to save its long random encryption key. Worse: it's impossible to transfer your history between Android and iOS! Worse: the backup file grows forever—incremental backup is impossible. The developers arrogantly regard these problems as irrelevant? Not suitable for long-term use :(

The app itself is fine and works the way it should. However, it has severe limitations with data backup and image handling - if you enable data backups to Google drive for example, it backs up the entire history as one huge file, and fills up all your storage space by moving each previous backup to the trash. Instead, it should perform incremental backups. Also, sent and received images do not have the option of being saved to the phone gallery automatically. At least give us the option!
