Unfortunately none that I would know of.
I once tried to port the code for android and I got some of it working but it was very unfinished and I'm not sure where the code is now... I keep trying to port the code into C++ to get rid of the java dependency, and to get ability to use the same code for windows and android but I'm not even 5% done with that...
The site has had quite low amount of active users the last 5-8 years and I've gotten more into vr lately, and a real software dev job, so I haven't had a lot of time, energy and motivation to work on the conversion... If it seems like there's a lot of interest for that I might continue working on it
