I like it for market data. It's mainly supposed to be a marketplace for graded trading cards, but doesn't seem a lot of people use it to post their cards. They're some, but more people using it would quickly improve that. It's best for looking up a specific card or player for market data. It tracks sales across platforms like ebay, myslabs, and several auction houses and gives you an average value based on card grade. Also, it shows each cards graded population across psa and beckett.

got some good deals but the auctions are super weird. I been bidding on 1 item that never ends just resets. some auctions take hours to end, some just reset for another week when u already had a bid. I dont know maybe im misunderstanding something but I dont dislike the app but I have a hard time recommending it just because of the auction timers are so unclear

Updated. App is trash now, can't keep up with current sales and consistently freezes. Looked up 10 cards and all of them were missing recent sales, by months not days. I've quit using the app and will uninstall if the next update does nothing.
