Fungelo

A daily map of where wild mushrooms are growing across 12 European countries.

Built from public weather, soil and forest data, with an honest confidence label on every score.

Live on the web and Android

The Fungelo map: named forest areas around Freudenstadt, each with an activity score from 61 to 79, and the scale from very low to exceptional at the bottom.
Sample data · Freudenstadt, Germany

A new map every morning

Every morning a pipeline reads public data about the forest, scores mushroom activity and shows it on a calm dark map.

  1. Reads

    Public weather forecasts, station data, soil moisture and forest maps.

  2. Scores

    Mushroom activity from 0 to 100, for each mushroom type and each named forest area.

  3. Shows

    Today and tomorrow, with an outlook a few days ahead. Every score carries its confidence.

Mushroom activity. A score is an index, not a chance.

Who it's for

  • Walkers, families and recreational pickers

    A better-informed choice of forest before they leave home.

  • Experienced foragers

    Deciding when to go.

Worth a closer look

  • One forecast per area, not per pin

    Fungelo shows named forest areas, never anyone's finds or spots. Your own places stay on your phone.

  • Confidence with every score

    Each score says how sure it is. Every mushroom type and rule is checked against past seasons, with a test written down before it runs. A type that doesn't pass stays at Low confidence instead of being oversold.

  • The rules of the forest, built in

    Protected and restricted areas are hatched on the map, with each country's and region's own picking rules.

  • 12 countries, 11 languages

    Slovenia, Austria, Croatia, Czechia, Slovakia, Germany, Poland, the Netherlands, Belgium, Luxembourg, Denmark and Switzerland.

    The app speaks English, Slovenian, German, Czech, Slovak, French, Croatian, Dutch, Polish, Danish and Italian.

    Each new country runs through the same repeatable process: data sources, rulebooks, builds, review and validation.

  • One codebase for web and Android

    A React PWA wrapped with Capacitor. Accounts on Supabase, subscriptions through Stripe on the web and Google Play Billing on Android, and the daily data published to Cloudflare R2.

  • Built by one person with Claude

    Coordinated across many parallel sessions. Related project: session-orchestrator.

In the app

  • The sheet for the Großhahnberg area: a score of 75, very high, with medium confidence, declining over 3 days.

    Every score says how sure it is.

  • Why this score: recent rain, moist soil, the right temperatures, suitable habitat and the main season.

    The weather and soil behind a score.

  • An area sheet comparing today's conditions with a find recorded on this phone, and the Natura 2000 site the area lies in.

    Each country's and region's picking rules.

  • Saved areas, each with today's and tomorrow's score and its confidence.

    Saved areas, today and tomorrow.

  • A user's own place, marked Only on this phone, with today's and tomorrow's conditions.

    A place of your own.

Have an idea that needs building?

I built Fungelo with Claude, from the daily data to the app on Google Play. If you have an idea or a product to bring to life, I would like to hear about it.
