I am a player collector and spent the time putting in all of my game used cards and auto cards and so on. It helps me know what i have without going and thumbing through them all. It does need an update tho, this app can go so many different places and could be a must have app for any sports card collector. But now... Not so much. Me personally, I wish there was a way to sort by auto, game used, serial #ed and so on. But overall a good app for a small purpose but could be soooo much better its not even funny.
