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

The app itself is fine and works the way it should. However, it has severe limitations with data backup and image handling - if you enable data backups to Google drive for example, it backs up the entire history as one huge file, and fills up all your storage space by moving each previous backup to the trash. Instead, it should perform incremental backups. Also, sent and received images do not have the option of being saved to the phone gallery automatically. At least give us the option!

I've had absolutely no issues using Signal for everyday texting. It has all the features a modern text platform has, including voice recording, image and video sending, gif support (not sure on stickers) and both audio and video calling features. It's never crashed on my phone, has always been snappy and responsive, and stays out of your way. All of this with the added benefit of peace of mind knowing your conversations are secure makes this my go to messaging app, couldn't reccomend it more.

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.)

What’s new

★ Now when you link your primary Signal device to a new Desktop, you can bring your chat history and your last 45 days of media with you. The transfer process is end-to-end encrypted, and completely optional. When it comes to making the choice about whether or not to leave the past behind, you're left to your own devices.
