Marbles is the only place on the web built specifically for Pokémon Marbles collectors. Log what you've got, see what's missing, and stop guessing whether that one in the bottom of the tin is a duplicate.
Tick off the marbles you own. The full set is there, ready to fill in. No spreadsheets, no photos in camera roll.
Instantly know which marbles you still need. Take a clean wantlist to the next swap or shop without scrolling Reddit threads.
Mark how many of each you have. Surface the ones you can trade away. No more rebuying marbles you already own.
Built as a fast, mobile-first web app. Open it in any browser, no app store, no install. Your collection syncs with your account.
The Pokémon marble craze caught us off guard too. There was nowhere to track them, so we built one. It's free to use. If you find it useful, tell another collector.
