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.

UPDATE: Signal just released scheduled/delayed messaging! I stopped using Signal when I switched to a new phone, so I'm not totally up to date on current features, but I wanted to update my review when I saw this. ------- Great app! Though I really miss some of the many features Pulse had to offer (scheduled messages, delayed sending, wide array custom color options, multi photo sending, etc), I'm really enjoying Signal! Solid app that has potential

So easy to use. Simple set up. iPhone users have some extra steps to make it work and they can't use it to send messages to just anybody only signal users. Android you can use it to send anyone and it will let you know which ones have the app and which messages are secure. Update: since the update It is totally broken. Just keep saying updating and it will not open. Very sad

This is the superior messaging and calling app. I love being able to send high quality images and video to friends, and it's insane how private and secure the app is. It's so easy to set up and it's very visually pleasing and customisable. I just wish they weren't ending support for SMS and MMS messaging. I understand why, but I really don't think it's worth it. It's so much easier to convince people to join when it simply replaces their texting app, rather than being an additional app.
