orecast: Minerals & Fossils
Rockhounding & treasure maps
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: lay old maps and aerial photos over today's map and blend between them. Plus the hex map showing where a lot is recorded. Now also on iPad.
There is more under your feet than you think. Ores and minerals, fossils, old adits and spoil heaps from the mining days. orecast shows you on the map what is documented at a place, and tells you where the information comes from. The data comes from official geological surveys and open research databases.
NEW: MAPS YOU CAN BLEND
Under “Maps” you lay aerial imagery, relief, old maps and old aerial photos over the map, up to two at once, and blend between past and present with one slider. Old maps are available where the German states release them freely. Aerial imagery and old maps are part of orecast Pro.
NEW: THE HEX MAP
Hexagons within 5 km show where many fossils, ores or mines are recorded. A coloured edge warns of WWII sites and marks protected sites. They show where a lot is recorded, not where you will find something. With Pro.
TAKE AN AREA WITH YOU AND THE HEATMAP
Save your area to your phone beforehand, and the map, sites and ordnance warnings keep working without signal (one area with an account, several with Pro). The heatmap shows in colour where a lot of mining, ore or fossils is recorded.
HOW IT WORKS
Tap a spot on the map or let GPS find you. The profile shows what is documented within 5 to 50 kilometres. You can share a place, for example in a message. The app starts where you left off.
WHAT YOU FIND ON THE MAP
• Gold, silver, copper, fluorite and dozens of other raw materials, each with its source
• Fossil sites with their geological age
• Caves, old mines and show mines
• Ore veins in Saxony and coal seams in the Ruhr and the Saar
• Castles, battlefields and bunkers, plus warnings about unexploded ordnance
• The relief scanner from official laser scans: ditches, banks, mining pits and spoil heaps, even under woodland
• Aerial imagery for Germany and Austria
• For every orecast episode the place from the video, plus a place of the week
• A note at low water on the Rhine, Elbe and Danube, with the hunger stones on the Elbe
HONEST, NOT PROMISES
orecast separates what is documented from what is merely possible. No invented percentages, no treasure promises. If the data is thin at a place, the app says so. Where old battlefields suggest unexploded ordnance, the map warns you. Adits and shafts are deadly. Never enter them.
AI ASSESSMENT AND PHOTO IDENTIFICATION
What would I find here? The AI assessment explains the local geology in plain words, from the data at that spot. Take a photo of a rock or a fossil, and the AI suggests what it might be. Neither comes with a guarantee. With a free account your first three AI uses are free.
MY FIND BOOK
Your finds with photo, type, date and note, as a PDF if you like. The exact spot stays visible only to you. You can record a find without signal, it uploads later. If you like, you can show it to other collectors. It then appears after a review, coarsened to about 5 kilometres.
KNOW BEFORE YOU DIG
Collecting and digging are regulated almost everywhere and often need a permit. Respect nature protection, archaeological monuments and private land. orecast provides information, not permission.

New in 1.0.13: a tidier map picker and an easier way to Pro.
Map picker
The left button stack now has a “Map” button. Choose the background (map, grey or aerial), add terrain relief in three strengths, and use “Past” to move along a timeline to old maps and old aerial photos. One slider blends between past and present. Everything sits in one place, leaving more room for the map. Aerial imagery, old maps and old aerial photos are part of orecast Pro.
Pro made easier
The Pro offer shows the benefits that fit what you are looking at. You can now buy without an account and create one afterwards.
Also new
• On first start you can also pick “Aerial photos” as an interest.
• Links to orecast.app/app open the app directly.
