About this app

Boletus predicts where and when mushrooms are likely to grow — before you drive out to find an empty forest.

Most foraging apps just show you where other people have already checked in. Boletus is different: it combines high-resolution satellite data (down to 30m), real-time weather, and soil science to score any spot on the map for the mushrooms you're after — refreshed every day, up to 5 days ahead.

WHY BOLETUS
The rain came ten days too early. The soil never warmed up in time. Other apps only show where mushrooms WERE found — nothing about today. Boletus fixes that by combining:
• Static layers — soil type, pH, tree species, canopy — that set whether a spot CAN support a species
• Dynamic layers — moisture, temperature trends, season timing — refreshed daily to show where it's happening RIGHT NOW
• Individual models per species, because porcini and chanterelles need different conditions to grow

KEY FEATURES
• Daily satellite weather data
• 5-day forecast, so you can plan before you take the day off
• High-resolution maps — down to 30m
• 10 of Europe's most-foraged mushroom species, each modeled on its own ecological requirements
• Growth condition score on an easy 1–10 scale for any point on the map
• Save your favorite spots privately — visible to no one but you

HOW IT WORKS
1. Pick your species
2. Check the score — a 1–10 probability rating, updated every day
3. Plan ahead — scroll forward 5 days to see conditions shift
4. Mark your spots and come back to them any time

BUILT ON REAL SCIENCE
Boletus is built on the same data science used by soil scientists and forestry agencies — Copernicus satellite data, the WRB soil classification standard, and the World Data Center for Soils. It's a probability score, like a weather forecast, not a guarantee.

YOUR SPOTS STAY YOURS
No check-ins, no community pins, no spot-sharing. Every score comes from environmental data and science patterns — never from other users' locations. Your saved areas and trip history stay private.

WHERE IT WORKS
Live at launch in Poland, Czech Republic, Slovakia, Estonia, Latvia, Lithuania, and Hungary — with Germany and Finland coming soon.

Know before you go — download Boletus and check today's spots near you.
