Orb has finally released an android app and unfortunately the results could be better. I tried the free version which has limited functionality but will give you a good idea of the program. I did not try audio only streaming or picture and file viewing.
I was unable to get audio on any video stream i tried. To be fair i occasionally have this issue with the browser version. The picture quality was far inferior to the browser version. This is the deal breaker for me. This must be improved before i will pay for the program.
I also had some force close issues which I'm sure will be repaired in later versions.
The bottom line is they must improve the video quality.
