BwMessenger is a secure messaging app designed for the Bundeswehr. It is based on the open-source protocol Matrix and offers users a familiar messaging experience with added convenience features. The app ensures maximum security and user-friendliness, allowing users to communicate with each other in a 1:1 chat or discussion groups, exchanging text messages, audio and video data, and documents. The app encrypts every transmission automatically, and all content is stored persistently and encrypted with the user's private key, ensuring data privacy.

BwMessenger offers users added convenience features such as targeted quoting, content liking, and rewarding exceptional contributions with applause. Polls and voting are helpful in making quick decisions, and attachments keep everyone on the same page. The app's rooms feature allows users to join discussion groups relevant to their interests, ensuring they never miss important information.

The app is easy to navigate, and with the integrated search feature, users can easily find other users without sharing personal contact details. The app also allows users to contact the User Help Desk of BWI in case of any issues or queries.

BWI GmbH continues to develop the app, promising more features in the future.
