Every tick, count, want and deck lives in this browser on this device. No account, no sync, no ads. Export JSON to keep a copy.
Which cards of a set you own and which are still missing, ticked off in this browser: the English card list built in, copies counted, a want list, and pasted decklists that say what is short. No account, works offline, no prices. Free, local, JSON and CSV backup.
Mtgpad is a checklist you keep by hand, not a portfolio and not a trading service. It shows no price, no market value and no collection worth, never reads a card with a camera, and asks nothing of anyone while you tick. It is not made by or endorsed by Wizards of the Coast. One device is one checklist, and the export is how a checklist travels.
