Ratings and reviews

ads every other screen as a response to the developer's response - I know it's a free app, I know that you need to make money, but a full screen captive ad every time you change the screen is a bit much. run passive ads and an OCCASIONAL captive ad. otherwise, people get annoyed and leave you bad reviews. hope that helps!

2 sets of ads and a "upgrade now" before I could even scan something.

could find a connect device. rather failed the purpose of the app
