Hello sir!
I can test your App in Android 5.0.1,
your Software on Ubuntu 15.10, Windows 7, Windows 8.
All tests will be done in 1 day, after that i'll send you a complete report of the bugs (if any) i'll find and some suggestions about layout/content improvement.
Milestone will be released after you will read my report.
Have a nice day, Domenico.
