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.

As a messaging app on the phone, I have no complaints! Good reliability, good for sharing photos as well! Audio calls are quite good as well. However, I think it is subpar for video calls. Bad experience compared to alternatives honestly, although I appreciate the privacy anyway. The Windows app is less reliable and has more issues with photos especially. Not a part of this review but may be relevant for some who want a unified messaging platform across devices.

My only complaint is I wish I could receive/send my normal text messages on the desktop app as well. Maybe you can do some kind of proxying/bridge thing through the app on the phone. You know Google's messaging app has a web interface option that lets you send and receive SMS from the desktop. I'm not saying you have to do it that way but I am saying add normal SMS text messaging to the desktop app please!!!!!

As far as I know, Signal has the best security and anonymity implementations amongst the popular the popular chat clients. Unfortunately, it has not been perfect for moving from phone to phone though without losing messages. I can't see historical chats from before the transfer on my new phone! That said, it's been a solid app. I can share messages between my laptop, iPad and phone without missing a beat.
