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.

What’s New

Version 5.22.1

• Fixed some issues related to notifications
• Try out the new 'send messages' permission to restrict who can send messages in your groups. Great for organizing an event, making an announcement, or just shouting from the rooftops. All members must be on the latest version of Signal for the setting to appear.
• We know you love speed (and we don't mean the 1994 blockbuster hit starring Sandra Bullock), so sending messages is now faster than ever.

Help me

Thank you for adding updates continuously and trying to develop the application ... We want to add Emoji such as WhatsApp, add themes for the application, add the call feature through the barcode, and add the feature to select all when deleting conversations

Needs to be more user friendly

The app is still under par from its competitors on iPhone as far as user friendliness is concerned .
There is no message forwarding option to more than one contacts. You have to copy paste for each contact. No short cuts available on iOS. You can not remove a participant from a group as administrator if he is added by mistake.
Please improve upon these observations.

Need clearification

I need to know. As u mentioned that u are just taking my phone number for app functionality. Therefore how come i am receiving notifications when ever anyone from my contacts joins signal. As you have not mentioned that you are taking contacts or not. So i need to know either you are taking contacts and telling to Apple Appstore or you are not taking them at all.
