No. Grzybiarz is an assistant, not an oracle. It shows the most likely species with calibrated confidence, features to check, and toxic lookalikes, but the final decision to pick and eat is yours, at your own responsibility.

Yes. Fruit-body detection, species recognition, and maps work fully offline, on your phone. A forest with no signal is exactly the environment the app is built for.

No. The models run on the device, photos are not uploaded. Your finds and routes stay locally on your phone; you can export them to a GPX file as your own copy.

The app returns several most-likely species with calibrated confidence and a checklist of morphological features. It is a hint based on a probabilistic model, not a verdict, you always see why the model is confident, or why it isn’t.

The full feature set (camera, litter detection, and offline maps) runs on Android and iOS phones. The web version is for browsing the atlas and learning.

Over 100 Central European species with descriptions, seasonality, habitat, and diagnostic features, compiled from mycological literature.

No. It helps you build knowledge and flags risks, but it does not replace experience or consulting an expert. When in any doubt, have the mushroom checked by an expert.

Critical pairs (for example penny bun vs Satan’s bolete, or parasol vs death cap) are always shown next to the recognition result, with an anatomical feature comparison. You decide with full context.

During the beta test it is free to use. Details of any paid plans will be announced in advance, before launch.
