Binder Buddy

For a long time I've been frustrated that no existing price tracking app is a complete solution. Nobody has all English cards, all Japanese Cards, AND all promo cards. I created Binder Buddy out of this frustration. Our database updates daily with TCGPlayer and eBay's prices singles, promos, sealed product, and let's you add them to your binder to keep track of them. If it's on TCGPlayer or eBay... It's on Binder Buddy! Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
