Are there any quality OSX desktop and/or mobile clients which interface well with Redmine and provide more use ability than simply an ATOM or RSS feed?

I know that Redmine lists several desktop and mobile interfaces on their wiki but I've tried all of them for iOS and OSX and am not impressed.

I've been using Redmine for a while and love it, we just migrated everyone over to it today and I received numerous requests from the team for a desktop interface.

I found a project on GitHub which wasn't listed on the Redmine wiki and it was the best I'd tried, but was still rather useless. Thought I'd check to see if anyone is working on this or if there may be a little known good client someone knows of.

Thanks
