Cache Companion 作者： GeoTrek

Cache Companion helps geocachers track progress on grid-based challenges without leaving geocaching.com.

Jasmer Challenge — find a cache hidden in every month since May 2000. Cache Companion shows your status next to the hidden date on every cache page and map preview.

Fizzy Challenge — find a cache for every Difficulty/Terrain combination (9×9 grid). Your status appears next to the D/T rating on cache pages.

Dashboard — a full year×month grid for Jasmer and a 9×9 D/T grid for Fizzy, both with clickable cells that open the map filtered to caches you still need.

Import — load your My Finds Pocket Query GPX file to populate all data locally. Nothing leaves your browser.

Toggle challenges on or off individually. Supports light and dark mode.
