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.

Great app! Wonderful way to connect with friends around the world. My only suggestion for improvement would be to record videos by hitting a button to start recording & then hit a button to stop verses having to hold down the record button the entire time. Also there is an unknown time limit (3 minutes?) where the video recorded is too long to load so it goes away & you have to do it over. It'd be nice to have a countdown to know when we're getting close. Other than that, we love it! Thanks!

Texting is good. I'll talk about video calls mostly. First of all, there's a major common bug that happens during video calls, the bug makes the toolbar disappear so you can't mute, hang up, and so on, I haven't been able to reproduce it 100% of the time, however it seems to happen after a long video call, usually after you open a media picker in some other app. Another issue is that when switching to another app, video becomes laggy. Also the UI is a bit unintuitive, and please add screen share

I love the app, but the only gripe I have with it is that it has not been syncing right away when messages are sent. There is a huge delay or sometimes never goes through. This is my third phone and same issue with me and my wife's phone. Update 03/01/2024 Since the past few weeks and with the updates, the app keeps sync randomly, and the messages aren't going through or they go after a huge delay. The photos get stuck in download mode and have to restart the app several times.

We're introducing new ways to keep your phone number private on Signal.

• Your phone number will no longer be visible to anyone on the latest version of Signal unless they have it saved in their phone’s contacts. You can change this in Settings.
• You can now set and share an optional username to let people chat with you without giving them your phone number.
• A new privacy setting lets you control who can find you by your phone number on Signal.
