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.

Many messages not going through. Have used this for about a year without issue. Lately, many messages don't get through, especially during long conversations. Have to switch back to regular texting app. It doesn't matter how secure the text is, if it never makes it through. Samsung Flip 3.

The good: Works well when it works. Excellent way to send full resolution photos SMS or over data. Like iMessage for the rest of us. The bad: Zero customer support. People cannot hear me on either audio or video calls. I have reached out to customer support more than three times and I have yet to receive any response.

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!!!!!
