About

Tattis is a forecast app made for mushroom foragers that shows where and when mushrooms are likely to grow. The app combines forest type, soil, terrain and up-to-date weather into a species-specific mushroom map covering all of Finland. Map shows where they grow - Species-specific heat map based on the combined effect of growing location and weather - Daily updated forecast – the harvest follows the Finnish Meteorological Institute's weather data - Forest type layers on top: grove, herb-rich heath, mesic heath, sub-xeric heath, xeric heath, barren heath - Works offline in the forest – maps are stored on your phone, no signal required Notifications when harvest time arrives - Push notification when a species' harvest begins or improves - Choose yourself which species you want to hear about - You won't miss the best days when conditions align Personal mushroom journal - Save your own finding spots on the map as private - If you wish, share your observation to the Finnish Biodiversity Information Facility (laji.fi) with one tap - Browse your past trips and locations Comprehensive species selection - Tattis knows 32 species – all edible mushrooms recommended by the Finnish Food Authority plus other edible specialties Reliable sources - Species descriptions: Luontoportti and Arktiset Aromit - Occurrence data: Finnish Biodiversity Information Facility's open data (laji.fi) - Weather data: Finnish Meteorological Institute - Terrain and soil data: National Land Survey of Finland, Geological Survey of Finland, Natural Resources Institute Finland Privacy first - Tattis doesn't track you.
