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.

Ratings and reviews

I have been using Signal over two years now and it is my go to messaging app. It is simple, has all the features like group messaging, and it is highly private. I like that I can take pictures to share within the app and they aren't automatically copied to my phone or the cloud. No complaints whatsoever, though it seems not enough people know about it my age. I encourage my friends to switch from messenger and WhatsApp

This is the perfect communication app! Video calls, texts, regular calls, even disappearing messages if you so desire. Fast and feature loaded, Ive never had an issue. The app is open source and with end to end encryption I never have to worry if my data is being harvested or shared without my explicit consent. Keep up the good work! Thank you

Overall, I've been extremely happy with this app for the past few years. But for the past week or so, the notifications stopped working. I'll open the all, and see I was messaged a few hours ago, even 20+ hours ago, and never got a notification. My battery saver is turned off, I've cleared the cache, restarted my phone, and turned notifications on and off both in the app and in android settings. Nothing fixed it. This is my primary messaging app, so I'm hoping an update will fix this soon

What’s new

★ The new and slightly refreshed Signal logo can help you digitally experience the feeling of seeing a good friend right after they get a haircut (but it's not a completely new hairstyle).
★ Chat folders let you organize your organizations, group your groups, and individualize your individuals into unique folders that are easy to customize and rearrange.
