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 40 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.

Secure text that doesn't require an email address to sign up for a login. That's a win! The security comes first with this app, which means it is harder to do some simple things like switching phones, and impossible to do others, like using the service on multiple devices. This app is mobile first. Wish there was a mobile version of the desktop app, so multiple devices would work.

Everything is good. The only annoying thing is when someone sends a message, and then another, or multiple, your ring tone does not stop. It overlaps. It's terrible. I had to mute it and now I forget to text back because I turned off Notifications so that I don't have to hear my ringtone constantly going off. Otherwise I like the app.
