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

I've used this for a couple of years and it's been very stable. Highly recommended! You can link your profile to other devices, however if you uninstall and reinstall, the other devices are going to be orphaned and old conversations will be lost when you relink. that includes any multimedia you've shared that didn't exist outside of the chat. like voice bites, pictures taken with the built-in camera control etc.

It's a great app. Easy to use. I like that it keeps personal info private. I enjoy the fact that you can use different backgrounds for each chat and i also like that you can change the text bubble color. I think the only little thing that I would change is a bigger color spectrum for text bubbles. But i would definitely recommend this app.

Edit: 12Dec2022 - Dropping to one star. Why do I need to relink to devices after an update?? I can't see messages sent from one device on another. It may be because messages are not retained on servers by Signal once they've been delivered. But come on!! Prev. Edit 2021: Dropped it from 5 to 2 stars. 1. Lost messaging history after upgrade. 2. Continual FORCED upgrades. Unable to use app without upgrading. 3.Need to resync with laptop after each upgrade. One step away from uninstalling!
