I am the maintainer of two Android mobile application, MQTT Alarm Panel and Wallpanel.

https://community.home-assistant.io/t/mqtt-alarm-control-panel-for-raspberry-pi-and-android
I am looking for an individual or individuals to take over these projects. WallPanel is very popular for displaying the Home Assistant home page. Alarm Panel integrates with the Home Assistant Alarm component and the Alarmó.
Update
WallPanel has a new repository and maintainer. The new repository is located here https://github.com/TheTimeWalker/wallpanel-android. Please follow the progress on that Github page.
