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.

Ratings and reviews

Video calls aren't the best and nor our voice calls. Many times I've called and it hasn't even ring on the other person's end. But it will missed call. And there's times that they call me and the phone doesn't ring but it'll show missed call. Other times I'll send a text message and it'll only show one check mark. But then when I send the next message it pushes the last message through. So that one gets double check marks. But the one I just sent has a single one. It's really strange

The most secure option to replace other more well established apps. BUT: The daily backups are VERY large and take FAR too long to upload to a cloud drive. An integrated incremental cloud feature would be nice!! It has happened many times that the app doesn't open and I need to restore it, this way LOSING 1 day's of data!!! This should NEVER happen!! At least there should be a desktop app syncing of messages (or merging backups between mobile and desktop app!!) 🤷

I really believe in this app! It's really refreshing knowing that I don't have to communicate in a panopticon. And the UI is simple and clean. However, the video calling feature is glitchy and has crashed and frozen a few times since the 10 minutes I've had it. Definitely some work to be done, but very happy so far.

What's new

★ The new and slightly refreshed Signal logo can help you digitally experience the feeling of seeing a good friend right after they get a haircut (but it's not a completely new hairstyle).
★ Chat folders let you organize your organizations, group your groups, and individualize your individuals into unique folders that are easy to customize and rearrange.
