UPDATE: 01/05/16
I left a pretty unfair comment to this answer out of frustration and need to clarify my position.
a. No it did not work initially for me using the app BUT Arvydas did reply in a timely manner to my email first and then here. It is already at a place that some or most functionality is possible and Arvydas has already reproduced the error. It’s not a 1 minute solution and I need to remember that.
b. Maybe I should learn Python? I now see an opportunity whereas before I only saw frustration and a non working app.
c. The app does need some documentation. I think it should be interactive like current mobile, tablet and certain desktop walkthroughs but I’m biased since I do prototyping with Principle, Proto.io and Invision.
So it appears the app does work but has a few bugs. However if Arvydas is as committed to the app as he is in helping me fix this issue things will get better. My apologies for being so quick to condemn the app and his efforts.
