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 messaging app and super easy to set up. My only complaint, and what I would improve is the image selection screen. It closes after you select one image, and you have to select the plus to go back in if you want to add multiple. It would be better if the gallery selection stayed up until we select add or done.

App is reliable and works well, but I really wish I had more control of some app behaviors. For example, if I respond with in line notifications, it just begins a running conversation in my notifications. I can see why some might like this but I really wish I just responded and the notification went away like most other sms or messaging apps work. I don't have the option to do this. I also wish that the app would always take me to the "home" screen instead of returning to the last chat I was in.

Great secure app, can't figure out why it doesn't ring with calls intermittently. I do get a notification that I missed a call, but it didn't ring. I've checked all my notification settings, and it does ring about half the time. The person who is calling says it rings and rings for a long time before it says I'm unavailable. Not sure if it is being interrupted by another background app?
