Tell the app the return you want: 1.75× if you sell in volume, 3× for a solid flip, 10× if you only want home runs. Set a minimum value so cheap items stop after the quick check. Every report works out the most you can pay and still hit your number.

They come from recent sold prices, not asking prices, and the app leans conservative. It's research, not an appraisal: check anything important, especially authenticity, before you buy.
No app can authenticate from photos. Reports point out what to check for that kind of item and when it's worth paying an expert or a grading service.
It's free for invited testers. Each tester gets a set number of credits: a quick check uses 1, and a full report uses 4 more.

They're used to research your item and aren't kept on our server after the scan finishes. Your saved items and photos stay on your phone.
