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

It is decent, but needs work. For one, I can't jump to a photo when viewing shared media. I have to scroll all the way up to the image which costs valuable time at my work. Secondly, my notifications for the app seem to be not working- often not notifying me of calls despite having Do Not Disturb turned off. Happened to me today which nearly cost me my job. Otherwise, it is decent. Though I prefer Telegram as it offers what this app doesn't.

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.

What’s new

★ We added a convenient shortcut to quickly lower your hand after you start speaking during a Signal group call. It's hands down our favorite feature in this release.
