AI terrain analysis, LiDAR mapping, historic topo maps back to 1879, and instant coin and relic ID — built for gold prospectors and metal detectorists who'd rather spend the day in the field than figuring out where to go.
7 days free, every feature unlocked. Then $8.99/mo or $89.99/yr.
Trained strictly for gold prospecting. Snap a photo of a creek, cut bank, or hillside — get a 0–100 score with confidence level. The model identifies rock types, calls out mineral indicators (iron staining, quartz veins, black sand), reads water flow for gold trap potential, names the deposit type (placer, alluvial, hardrock, eluvial), and tells you where in the frame to start sampling. Plain-English explanations included.
Photograph a coin, button, buckle, nail, or anything else you pull out of the ground and get an identification: what it is, the years it was made, what it's made of, and the history behind it. Built to be honest about uncertainty — when a date isn't legible in the photo, it says so and tells you where to look instead of guessing. It never gives a dollar value or an appraisal. Every result saves to your device, so the finds add up into a record of what you've dug.
Your AI prospecting buddy. Ask about geology, gear, technique, panning, sluicing, or whether that black sand is worth a second look. Trained on 30+ years of placer and lode prospecting knowledge — not search engines.
See what satellite imagery misses. High-resolution 1-meter USGS 3DEP LiDAR hillshade reveals the ground's history: old placer cuts, hydraulic pits, tailings piles, ditch lines, and water races invisible from the surface. Instant load across California, Oregon and Nevada, rendered on demand everywhere else in the US. Multi-directional shading keeps linear features like ditch lines visible no matter which way they run.
Scanned USGS topographic maps going back to 1879, laid over the modern world with an opacity slider so you can fade between then and now. Find the mill, the cabin, the wagon road, and the townsite that vanished a century ago. Three era layers: Oldest (1880s–1930s), Classic (1900s–1940s), and Detailed (1930s–1940s). Covers California, Nevada, Oregon, Washington, and Arizona today, with more states on the way.
Mapbox satellite, topo, geology, and public-lands layers. See claims, property lines, and access. Drop pins on cuts, riffles, foundations, and old workings.
Record routes, mark finds, log your hours. Plus a private gold log: every find with weight (grams or ounces), location, and notes — pinned on your map, never public. Watch your totals grow over time. XP tracks your posts, analyses, and gold logged.
Curated guides for beginners, deeper field technique for veterans, and news from the prospecting world. Hand-picked, no algorithmic clutter.
Share finds, follow people who've been working their patches for decades, swap technique. Prospectors and detectorists welcome. Moderated to keep it useful.
Locations and finds are private by default. Share what you want, hide what you don't. Honey holes and permission spots stay yours.
Canyons, back roads, the last ten miles of dirt before the creek. Download the ground you plan to work while you still have signal, and in the field the map runs off your phone with no service at all. Every layer comes with it, not just the basemap.
Browse the map, find a creek, an old homestead, or a likely site. Save the area for offline.
At the spot, snap a photo of the terrain. Get a 0–100 score and reasoning you can actually learn from.
Work the spot. Pan, sluice, dig, or swing the coil — the reason you came out.
Mark finds, track your route, share what you want with the community.
Every feature unlocked. AI analysis, GoldBot, LiDAR, offline maps — full access, no limits. No charges until day 8. Cancel anytime through your Apple ID with one tap.
Subscription auto-renews unless cancelled at least 24 hours before the trial ends. Manage in your Apple ID settings.
Built by a prospector for prospectors. Three decades of weekends working creeks with a pan, eight years swinging a detector, and a stubborn belief that the prospecting community deserves better tools and a real place to share what they find.
All features unlocked for 7 days. Payment method required up front (Apple ID handles the billing) — billing starts on day 8 if you keep it. Cancel anytime in your Apple ID subscription settings, no questions.
$8.99 per month or $89.99 per year. The annual saves you $17.89.
iPhone (iOS 16+). Android is on the roadmap.
Yes. Download the area before you head out, then tap the saved map in Offline Maps to activate it. A banner shows which area is live, and the map draws only from what you downloaded. Tracking and logging work offline too. Full instructions here.
No app can do that. We give you better tools to read the land — actually making the find is still on you.
Coin & Relic ID identifies what you found, what it's made of, and roughly when it's from, right from a photo. It won't tell you where to dig, but once you've got something out of the ground, it'll tell you what it is.
Prospecting: public lands open to mineral entry, and any claim you legally hold. Detecting: lands where you have permission. Rules vary by state — never on federal park land, often restricted on archaeological sites. Always know the local rules.
