About this app

Millions of people use Signal every day for free and instantaneous communication anywhere in the world. Send and receive high-fidelity messages, participate in HD voice/video calls, and explore a growing set of new features that help you stay connected. Signal’s advanced privacy-preserving technology is always enabled, so you can focus on sharing the moments that matter with the people who matter to you.

• Say anything – State-of-the-art end-to-end encryption (powered by the open source Signal Protocol™) keeps your conversations secure. Privacy isn’t an optional mode — it’s just the way that Signal works. Every message, every call, every time.

• Go fast – Messages are delivered quickly and reliably, even on slow networks. Signal is optimized to operate in the most constrained environment possible.

• Feel free – Signal is a completely independent 501c3 nonprofit. Development is supported by users like you. No advertisements. No trackers. No kidding.

• Be yourself – You can use your existing phone number and address book to securely communicate with your friends.

• Speak up – Whether they live across town or across the ocean, Signal’s enhanced audio and video quality will make your friends and family feel closer.

• Whisper in the shadows – Switch to the dark theme if you refuse to see the light.

• Sound familiar – Choose custom alerts for each contact, or disable noises completely. Simon & Garfunkel wrote a hit song about it in 1964, and you can experience the sound of silence whenever you want by choosing “None” as your notification ringtone.

• Picture this – Use the built-in image editing features to sketch, crop, and flip your outgoing photos. There’s even a text tool so that you can add more words to the 1,000 that your picture is already worth.

Love the app and I have been using it whenever possible! However, there are a few things that should be changed: 1) the possibility to schedule backups. Whenever my phone is performing a signal backup it becomes useless for over 10 minutes and this mostly happens at inopportune times, very annoying. 2) It should be possible to reply/react to individual pictures when these are sent in bulk. So far one can only react to the entire message but not individual photos in the message

Used to be a great app, but it has been taking near about 16+ hours for messages to be delivered and/or received. Before that became an issue, notifications wouldn't appear unless loading up the app. Something has gone wrong relatively recently, and nothing on my end has changed. Edit: Bumped to 3 stars from 2. Delays are less rare, notifications still an issue Edit 2 (3/9/23): Dropped to 2 starts again, don't receive notifications for exactly 7 minutes.

Signal was a great app. I have used for several years and part of that greatness was its integration with SMS. Because of that integration I was able to get a few friends to use it too. Because of signals terrible choice to remove sms support, I will be less likely to use and recommend this app. They have time to put Instagram like stories, but not keep a key functionality of this messaging app included.
