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.

decent, straightforward app but please let me turn off this awful suggested message thing. it's fine to have it as an option... please make it an OPTION. it covers the entire message you're trying to read and reply to and does nothing for me besides add difficulty when using this app. idk if it's AI or what but it is almost never actually relevant suggestions either...

Safe and secure messaging that EVERYONE should have installed. There is a reason it is the gold standard for encrypted E2E messaging. You may not get full fledge features and novelty things that you get from the open and less secure services (like telegram). But you do get a solid and usable messaging system that is 100% fully encrypted and able to keep your conversations and interactions private from outside snoopers, beat it government or data stealing corporations or other nefarious people.

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!

What’s new

★ We added a convenient shortcut to quickly lower your hand after you start speaking during a Signal group call. It's hands down our favorite feature in this release.
