orecastThree kinds of app, three purposes
The first group are photo identification apps. You photograph a stone and an AI names it. Handy, but treat it with care: in tests many of these apps return three answers for the same piece from three angles, and some demand a subscription after the very first photo. As a quick first hint they are fine, as the last word they are not. The second group are find maps. They show places where others have already collected, often with filters by mineral and with boundaries for protected or private land. The catch: the big maps come from the United States and are dense there but thin across Europe, and many entries are community pins without review. The third group are reference databases such as Mindat or the German Mineralienatlas. They are thorough and reliable, but they are lookup works rather than field apps, and awkward for beginners.
What actually matters
Four things separate a useful app from a frustrating one. First, honesty: does it clearly say what is documented and what is merely possible, or does it sell guesses as certainty? Second, the data source: official geodata or anonymous community pins? Third, law and safety: does it warn you about protected areas, private ground and old mine shafts, or send you out blind? And fourth, fair pricing, without a subscription trap after your first tap.
Where orecast fits
orecast is deliberately the honest option. The map keeps apart what is documented in official sources and what the rock only makes plausible, and it never gives percentages or guarantees of a find. The data comes from official geological surveys across Europe, from BGR and GD NRW through BRGM and GeoSphere to ISPRA, plus fossils from the Paleobiology Database. Protected areas, historical sites and hazards such as old mining or unexploded ordnance are flagged. And free use stays free, with no hidden subscription trap.
How to choose
If you just want a quick name for a stone, a photo app works as a first hint, but check the result against the real tests of hardness, streak and acid. If you want to know what genuinely lies in the ground around you and where you may legally search, a data-based, honest map is the better choice. That is exactly what orecast is built for, for Europe and without false promises.
