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.

The app is great! But I have a suggestion

Hi, I use Signal since 2 months after deleting WhatsApp, and I want to tell everyone that since using this app I discovered that is even better then WhatsApp. Signal have “Note to your self “ that is very useful tool to exchange info between your devices ( iPhone, iPad and Desktop) Only suggestion is to add in the feature update possibility to edit messages that was already sent. This option is already implemented in other messenger apps like Viber or Microsoft Teams. It’s very useful , because , sometimes, you are in a hurry and make some grammatical mistake Thank you PS. Your app is great. Keep going!!

Stop using WhatsApp and Facebook Messenger

The sooner we spread the word about Signal and its privacy protection via encryption, the faster we get away from the data-hungry Big Brother. Privacy is a human right that Facebook has never respected.

Would you still be friends with someone who watches you shower and listens to all of your conversations even when he isn’t in the room? Just get Signal and convince everyone to make the switch.

Edit sent message option!

I use Signal (& I like it) after WhatsApp “impose” the new privacy policy.
But I want to see an update with the possibility to edit a sent message, please!
I’m living now in Russia, where many people are using Viber and the edit message option is a useful tool they have implemented long ago.
Signal, please do the same!
