A foraging companion

Find.
Identify.
Save.

Grzybiarz is a mobile app for mushroom foragers. Its on-device AI helps you spot fruiting bodies in the leaf litter and suggests a species from a photo, and the app keeps a private map of your finds. Everything runs on your phone and works fully offline in the forest without signal.
