I have tried a handful of different tracking tools over the last few seasons, but I keep coming back to this pokemon card scanner app because the interface is so much cleaner and more responsive than the competition. There are no intrusive advertisements or clunky menus to navigate, which makes the process of scanning through a fresh booster box feel like a reward rather than a chore. The speed of the recognition engine is truly impressive, even when I am trying to catalog dozens of cards at a time in various different lighting conditions.
