Safe Messenger is an instant messenger for iOS and Android that stands out due to chat encryption
In 2014 I designed iPhone and iPad version helping my college who worked on Android version.
All four versions (iPhone, iPad, Android phone and tablet) share single visual style and use same UX and UI decisions if they don't come into contradiction with the platform guidelines.
Basic idea is very simple. If both users have this app their conversation is safe and automatically secured thanks to encryption.
Safe Messenger allows you to chat with your friends who use different instant messengers if those messengers allow it via API, but in that case the conversation shall be marked as insecure.
Every messenger needs a group chat and Safe Messenger is not an exception. Just tap "Create group chat" in pop up menu in top right corner and choose your friends:
You can find those group chats later in recent conversations list by special icons:
At this moment Safe Messenger project is postponed till better times right after beta testing because of the company's internal business matters. We hope to get it released in short time, because we received positive feedback during beta test and internal use.
