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

This app used to be good, but with each update there comes glitches or something is always wrong with the app lately. I receive calls from abroad. But lately since this last update.......the call button controls disappear and you can't get it back unless the call is ended. This is really annoying and it was never like this before. If you people are gonna improve and update, at least have someone who knows what they are doing. Very shít update, really!!!!!

I love the video call, media (pictures) and the excellent quality of all the app functions. I use Signal every day! January 2024...I have been using this for a couple of years now & have been very pleased with it. Recently it was updated, so now I can't find the reverse camera option. This is my "face to face" communication with my daughter & family (long distance), & the reverse cam allows me to send pictures or show them things during video calls. Please fix it?!

I love Signal. It's so much better than other messaging apps. It has much better and easier functions. Signal is only for smart people, who like simplicity, with encrypted security. I tried to get all of my not-so-smart contacts to use Signal, and only the smarter ones did. The others are still using their stock messaging app with little to no encryption, and no special functions. I can search threads for numbers and words, I can search only media, I can reply to any messages in the thread, etc
