About

Cepello

Features
Read full description

The forest leaves clues. Cepello reads them for you. For the species you pick, Cepello highlights every patch of Switzerland with a favourable biotope β€” then lays a weather verdict on top: "Good chances", "Possible", or not worth the walk today. THE ZONES For every 10 m square the app computes a score from 0 to 100 out of public data: relief, slope, aspect, forest type and tree species, geology, soil pH, vegetation belt. Each species has its own ecological profile, drawn from the mycological literature. The zones do not depend on the weather: they answer "where to go". THE WEATHER VERDICT The weather answers "when". Cepello combines the species' season, the rain of recent weeks and the forecast: enough rain followed by mild nights triggers a flush after a delay specific to each species. The flush index reads over 14 days. THE SPECIES Penny bun (porcini), chanterelle, morel, horn of plenty. YOUR JOURNAL Log your finds, with a photo and a position. Everything stays on your phone: no account, no server, and your spots are never transmitted. Export a backup whenever you like. FORAGING RULES Swiss cantonal rules and those of neighbouring countries, summarised, with a link to the official text that governs. FREE AND PREMIUM The free version shows the broad favourable zones. Premium shows every precise spot, what makes it good, and the 7-day forecast with the flush window. WHAT TO KNOW The zones are estimates: they show where the biotope is favourable, not where the mushrooms are. Cepello guarantees no harvest and does not identify mushrooms. Always have your pick checked by an official inspector before eating it. SUBSCRIPTION Cepello Premium comes as a monthly or yearly auto-renewing subscription, or as a one-time lifetime purchase. A subscription renews unless cancelled at least 24 hours before the end of the current period; management and cancellation happen in your App Store account settings.
