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

Great app, love the simplicity and privacy. Needs a couple of features to make chatting easier. First, it would be nice if I could set a default setting for whether my images disappear after 1 read or if they persist. I find myself constantly having to press the button to have it disappear after my image is viewed. Second, adding text on top of images is cumbersome. I'd like to be able to add text in a uniform way where I don't need to adjust size and color, only the placement, similar to Snap

I enjoy this app, it's a nice alternative to Facebook Messenger and it is supposedly encrypted. If you have friends on iOS and you're tired of photos and videos you've texted to them getting crushed so hard from compression, it makes it look like it was shot on a 2004 flip phone, give Signal a shot. It's been a great messaging app so far. I just hope we can trust them with the data.

Signal is a suitable app with some valuable attributes, but generally it's just typical. The customer experience is nothing special, and the user interface is rather fundamental. Voice and video calls are good, yet the quality is not the best. Personal privacy functions function as promoted but might be improved. In general, it's an okay solution, however there are far better ones readily available.

What's new

★ Show them the time of your life with new stickers in the media editor that let you add stylized time decorations on outgoing images.
★ Now you can easily select a different audio device during Signal calls. It's Bluetooth without the toothache (or the blues).
