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

Well it works great. For a secure app, it provides full backup and restore on a USB or direct transfer to another phone via wifi. The only issue I have is that it has to be tied to a phone number. I have signal on my PC, registered using my mobile phone. So why can't I add it to a second mobile device that has no phone number like a PC? Oh well. Can't winner all I guess.

What a fantastic App! I am very intrigued and very impressed. It works like a smooth charm. The App is in a very clean and healthy appearance. It really operates faster than you blink., especially when you delete a single item. Blazing speed never seen before. You can even YELL in there and no one will hear you. 👀 I really like the monthly donations to support Signal. You guys indefinitely deserve it for an top - notch service.

I love Signal except for one crucial, star-reducing issue: it takes a good 30 seconds to open All Media when attaching photos. It didn't used to do this, it used to be super fast, but there was one particular update when it got super super slow, and it never went back. The amount of media on my phone hadn't changed. I addition, I really miss the short period of time when link thumbnails would be downloadable as media. Please bring that back. But fix the first issue and I'll up the stars.
