## Description

Cache Companion helps geocachers track progress on grid-based challenges without leaving <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/463fae520be212271003f6b49cf1112c055b726d0611b2b2fabc20ed70e8ec02/http%3A//geocaching.com" rel="nofollow">geocaching.com</a>.

<strong>Jasmer Challenge</strong> — 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.

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

<strong>Dashboard</strong> — 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.

<strong>Import</strong> — 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.
