Monal IM UI

Modern UI for XMPP on iOS and macOS

Monal is an open source XMPP instant messaging client for MacOS and iOS which strives to be the go-to client for these platforms just like the app Conversations is for Android. Like other messaging apps on iOS and macOS Monal must deal with the limitations of these platforms. Yet, Monal is able to fully support push messages even for encrypted groupchats without resorting to non-XSF- standardized extensions to the long-lasting XMPP protocol.

Since Monal has a quite mature and stable XMPP backend now, the focus is shifting to rewriting the UI of Monal. And all this while adding new features, such as voice and video calls, which have only recently been added. In this project, Monal will receive a new chat UI that provides better UX and is way more maintainable for the developers. Additionally, the audio call functionality previously funded by NLNet, will be extended by a dialpad. This will allow calls to mobile and landlines via appropriated XMPP-VoIP-bridges like To speed up connection establishment support for Bind2 and FAST will be implemented. This will result in better UX, especially for users on mobile connections with low bandwidth and high latency.
