The gui needs some polishing up could be more intuitive.
The app and the windows software are not properly translated, on a german system some text was even displayed in greek letters not to mention some messages are in English some in german. Both at times clipped.
The program works ok though the connecting / transmitting + receiving process needs to be improved.
The transmission seems to be unencrypted.
