ChatSecure is a messaging app for Android and iPhone. The app is a secure alternative to other messaging apps like WhatsApp, WeChat, Line, Facebook Messenger, Google Talk and Threma. ChatSecure supports the Off-the-record (OTR) protocol for encrypting instant messages. When it is used together with Orbot your internet activities are also anonymised, making your online communications even more private.
