Who's Claim (BC)

An Android app for British Columbia gold prospectors and recreational claim stakers. See who holds the placer claim under your feet β€” and keep working when you're out of cell range.

What it does

Everything that needs the network (claim data, map tiles) can be cached, so the core features work fully offline in the backcountry.

πŸ“

Find Claim Here

Get your GPS position and check it against BC's mineral tenure data. Shows a satellite map with your position, the claim boundary, and the claim's details.

πŸ—ΊοΈ

Map

Full-screen satellite imagery centered on you, with place names, placer-claim boundaries overlaid, and a switchable second data layer.

⏺️

Track Recording

Record a GPS track β€” distance, speed, duration β€” that keeps running in the background with a live notification.

πŸ“‹

My Tracks

Lists your recorded tracks; tap one to see the route on the map.

Save your current location with an optional name (long-press for quick preset names).
