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.

Love signal! however I've noticed a bug to PLEASE FIX♥️: the calls do NOT ring, even with notifications on in the app, and in settings, and the phone in full ring mode. it's very frustrating because I keep missing calls. DEVELOPERS, PLEASE FIX AND I'LL BE VERY VERY GRATEFUL. i use it for a lot of my messaging and it's easy to back up messages.

I love the privacy, encryption and everything, but I hate the fact that my messages keep stalling even with fast internet. Often I would send a message out to a friend only for it to just... not send. Very annoying. Especially when you're in the middle of a conversation with your partner and have anxiety. Nightmare fuel ngl

Great app for messaging. I would have given 5* but for some reason, in the last two days, the time stamp on my messaging has been WAY out. The time stamp is over 3 hours behind my correct time, and 5 hours behind the correct time of the person I am chatting with. Updates have been done, so dont know the problem. Tried to contact for help, but between bug log and other info required, it wouldnt go through. Good app, with one little glitch at the moment.

What’s new

We sped up the performance of scrolling in long chats. If you are in a big gardening group, now bloom scrolling is also vroom scrolling.
