Threema
Threema is a new mobile messaging app that puts security first. With true end-to-end encryption, you can rest assured that only you and the intended recipient can read your messages. Unlike other popular messaging apps (including those claiming to use encryption), even we as the server operator have absolutely no way to read your messages.
Features:
- End-to-end encryption of text messages, images and GPS locations
- Contact synchronization: find other Threema users automatically
- Send images (three size choices)
- Share your location on a map
- Verify your contacts' public keys by scanning a QR code from their mobile phone, all within the app
- Network connection status at a glance: the color of the band below the navigation bar shows whether the app is currently connected to the server.
