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.

Ratings and reviews

Very good app. It's easy to upload pictures and other content, plus it displays them neatly within the chat window. Been using it for over a week with zero bug issues other than one: When trying to open a message from the lock screen, it freezes briefly, then the screen times out, and then I try unlocking the phone and it brings me to the content at that point. That's not an issue really for me, because it still works. Otherwise, it's great and I like the personalization settings.

I changed my rate from four to three stars, and this is why, no schedule messages are possible to setting up, and your app is a bit heavy more than 250 MB. It's impossible to delete a contact from my Signal contact list, just because the person in the other side has my phone number and I do not have that person phone number, that is ridiculous! I understood you dropped the SMS for privacy reason, but you really need to improve this application, in a better way. Thank you for your understanding!

Great backup app! But a pain to use bcs it's not all clear how to get contacts. I still can't add friends! Not very user friendly and it has too much guess work. But as a backup chat when others are down, it's just practical to have sitting on the side. So I gave it a 4 star for practicality, not for ease of use... they need to go back to the drawing board and make it more like or better than most other chats.
