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

I've been using it for a couple of years now. Excellent app and excellent quality. Picture resolution for sharing is high res. Great video quality. Secure/private communications, and the best part is they don't read all private messages, contacts, email, financial... like all the other messaging apps. Hats off to the developers on this app.

Signal is an amazing app. A few little features that I would like added to it would be: 1. Option to pin messages. 2. Tap and edit feature instead of tap and hold. (It's just faster that way) 3. Being able to send the stickers from the sticker pack pop up so that we don't have to go back to the sticker area again to find it. Please keep up the amazing work.

This is way better than the alternatives in my country, it's simple, even with the seemingly useless features like stories etc. The app doesn't have too much and looks pretty nice. Yet the only problem with this is that it drains too much from my pc and my internet, the problem might be on my side tho, but as far as I am aware and while checking if that's the flaw of the app, I found that it really messes with cpu and overloads the network slightly. Still a great app, looking forward for updates

What's new
