• 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 5.20.3

• 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 gave our chat bubbles a haircut. Thinner margins and shorter timestamps leave more space for your messages without sacrificing clarity.
• 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.

The best instant Messenger!! EVER!!!!

I’m just blown away by how awesome this app is! It comes with a few sticks and built in integration with Giphy!! I love Giphy! Can share GIF right from the app and now go to my web browser on a separate app to copy and paste a URL into the app! :) Plus the app is heavily secure for instant communication! Even recommended by Edward Josef Snowden! This level of heavy emphasis on security is welcomed largely. My only complaint is that the app could come with more stickers preloaded in the app or have a sticker store built right in to the app. All in all, I feel much secure using this app! Thank you all, the Developers, Donators & Everyone Who has contributed to this app! My best wishes to all of you! I’m optimistic for future, I want to see what else signal team brings to the table. 😃😃😃

Solid, secure, and now a far more polished instant messenger

Signal has always been a reliable messenger, and is regularly updated with big fixes, performance improvements and tweaks. It’s most recent update has given it a massive yet subtle facelift that now has the look and feel of a modern app, a great improvement over the previously dated (although functional and consistent) interface.
3D Touch shortcuts scattered about, a wide range of attachment options, and rock solid security make for a complete feeling messenger.
Always been able to recommend this app to those that want secure messaging, and with its new look it fits more in on any iPhone than ever!

Extra security and privacy features

Love this app, it's one of the 'must haves'

Being an app dealing with privacy, I would really appreciate a couple simple security and privacy features that are currently lacking in Signal for whatever reason..

--PW/PIN/Biometrics; to secure the app and/or individual conversations.
Unless I'm missing something anyone with physical access to your unlocked device can take a gander at your contributions and/or mess with settings, or even communicate with anyone..
Obviously any sensitive conversations should be deleted or have disappeared enabled and you should take more care to prevent unauthorised access to your devices, but still you never know, and it's just something I believe should be included in all apps and services that deal with potentially sensitive user information.

--Some kind of "quick quiet mode" to quickly silence and hide any incoming communications.
And status system that enables users to communicate the fact that it isn't necessarily "safe" to contact at the moment.

This ensures any sensitive and private communication is not seen or heard by anyone other than your self.

Thanks for an awesome app so far, I think everyone should be using this, even if you think you don't need to.
