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.

One of the better messaging apps for privacy and security, but after a couple days of using it I switched back to my unsecure app. I did this for three reasons: 1, no way to schedule a message; 2, doesn't sync with Link to Windows for integration with a desktop (I don't want a separate desktop app for Signal); 3, have had a couple messages not go through, and I need reliability. I may try again later, but for now it's just not there yet for me.

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 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!!!!!!!!!!!!!!!!!!!!!!!!

It's good for texting. My only hangups are that it doesn't sink up well with the Microsoft To Do list app, so you can't easily send curated lists to people, and also there's not much for stickers, gifs. Also it doesn't work to well on the pc either with Windows Phone Link. You can't pick up from the PC easily. You have to copy and paste links from the phone to get to a page sent via this messaging service. So while it's good for messaging privately, it's not the best.
