TOTK/BOTW Armor Tracker

Armor Tracker for BOTW and TOTK is a Chrome extension that helps you monitor which armors you've collected, their current upgrade level, and the materials required for upgrades. It displays images for all armors, lets you mark owned items, filter by name, and view per-level materials. As you adjust levels, the materials list updates to show what remains to fully upgrade.

Your progress is saved locally so you can resume later. This is an unofficial fan-made tool and not affiliated with Nintendo. The app originated as a web app and now extends to a Chrome extension for easy access.
