Millions of people around the world use signals daily for free and instant communication. Send and receive high fidelity messages, participate in HD voice / video calls, and discover a growing set of new features that help you stay connected. Signal’s advanced privacy-protection technology is always enabled, so you can focus on sharing the moments that matter.
Anything Say something – sophisticated end-to-end encryption (powered by the open source signal protocol) protects your conversation. Privacy is not an alarm mode – it’s a way of working on signals. Every message, every call, every time.
Go fast – Messages are delivered quickly and reliably, even on slow networks. The signal is optimized to work in the most constrained environment possible.
Free Free – Signal is a completely independent 501c3 non-profit. Development is supported by users like you. No ads. No tracker. Naughty Corsi.
Be Yourself – You can use your existing phone number and address book to communicate securely with your friends.
Talk to Ak – Whether they live across the city or over the sea, the increased audio and video quality of the signal will make your friends and family closer.
Shad Whispers – If you refuse to see the light, switch to the dark theme.
Familiar Known Words – Choose custom alerts for each contact, or disable words altogether. Simon & Garfunkel wrote a hit song about it in 466464 and you can feel the sound of silence by choosing “Nothing” as your notification ringtone whenever you want.
• Image it – Use the built-in image editing features to sketch, crop and flip your outgoing photos. There’s even a reading tool so your picture is already valuable that you can add up to 1,000 more words.
