The App did not work correctly on my Samsung A21, Idk why. There was no way to do & send a bug report on my system to see what the issue was. "However I did receive a speedy hassle free refund. Thank you!" Hopefully the problem resolve itself in the future, (I would like to try it again.) I am not quite sure, but I don't think that it fully installed itself correctly. Maybe a free test run, to see if it work's on your device 1st, would be a good idea. 😁 Totally love concept.
