Every part of Binder, broken down.
The features in this list are the ones we are most proud of. The rest of the app is the unglamorous plumbing that makes them work.
Binder reads raw cards and graded slabs in one shot, identifies the variant, and pulls live eBay comps for that exact card and grade.
Binder plots your whole collection. Or any single card. Across 1M, 3M, 1Y, and all-time, with the cost basis line layered on top so P&L is one tap away.
Binder writes a short, plain-English read on every card: what is driving the current price, which sales pulled the average, and what is worth watching next.
Every Binder price is built from recent eBay sales. Separated by grade, filtered for outliers, and linked back to the source listing so you can verify it yourself.
Different collectors, different needs.
If you collect Pokémon for the love of the cards, not the spreadsheet, Binder makes the spreadsheet part disappear. Track every card, find the holes in your sets, and know what your shelf is worth at a glance.
P&L tracking, cost basis, time-weighted returns, and a daily snapshot of where every position sits. Binder gives you the same view you get on a brokerage app, applied to your cards.
Players who keep current with the meta know that the difference between a Tier 1 deck and a Tier 2 deck can be hundreds of dollars. Binder tells you what your deck is worth and where the budget options live.
Whether you are running a part-time eBay store or clearing out a long-term binder, Binder gives you the comp-backed price floor and the recent sales pile under every card you are about to list.
