Free Pokémon collection tracker
A collection tracker should show what you own and what is still open — without a paywall on the list itself. nDEX is a free Pokémon TCG collection tracker: sets, gaps, and custom lists stay free forever. Open a set checklist, mark cards as you get them, and keep the same progress on this browser until you save a collection.
Free forever. The best collection site I could build for what I wanted from the others. Collection tools stay free, including new ones.
