Threema for Android gets a big update today. Threema's design has been refreshed and modernized, inspired by Google's new «Material Design». The app now also supports tablets with a multi-pane layout and allows you to acknowledge or answer messages directly from Android Wear devices such as smartwatches. The update 2.0 further includes:
Option to hide stale contacts (inactive for more than 3 months)
Material design inspired menus, toolbars, etc.
Redesigned navigation drawer
Floating action buttons
Combined notifications with picture/video preview
Search contacts in contact list
and much more
