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.

Ratings and reviews

Military preferred. Not great, but standardized. It seems like the encryption slows down it's performance. There are times when we have a message sent to us and the next day we say "No Sergeant, we didn't receive anything." Then 20 minutes later we all hear our phones chime at the same time for the late message. Then phone calls will not work properly. Usually we hang up and try via our non-encrypted apps which work just fine. This app also doesn't like hands free driving. (Still the same.)

It's encrypted end-to-end by default. It's free (made by a nonprofit). It's not owned by FB, G, or any other big ad pusher. And it does text, voice, and video. (Missing feature: "Mark as Unread"; I find I often take a quick peek at a message and find that it requires a lengthy reply that I didn't have time to write at the moment, but then forget to come back to it until much later.)

Great connecting app. Working well for what I need. We use this as the primary messaging app for church. It works great for forming and managing groups. You can easily make new groups, have someone leave the group, change several people if you want. Theie safety privacy concerns are great, but it does make backups a little bit more complicated. I just changed phones recently & I will say that the process of moving over to a new phone has gotten easier. M conversations moved over with me
