OpenRedmine is a free Android Redmine client that allows users to connect to Redmine 1.2 or later with API access key. This gamma release offers a range of features such as offline issue viewing, filtering, sorting, and viewing changelogs and relative issues. Users can also create or modify issue/timeentry and download files related to issues. The app also allows for viewing wikis and news.

Users can connect via gzip compression and basic authentication, and it also allows for connecting to unsafe SSL sites powered by transdroid. The app requires permissions for internet access and vibrate notification on tapping the list item. It is important to note that cache data (downloaded issues) is stored without encryption and needs to be removed manually by opening the connection list and selecting "remove all cache."
