Fungi Booklet is a specialized field guide for Taiwanese fungi, providing on-device AI identification and offline topographic navigation for hikers.
The App DNA
What makes this app unique?
It removes the connectivity dependency required by standard navigation apps, enabling safe exploration in remote mountain regions where cellular access is unreliable.
For Hikers, mountaineers, and amateur mycologists in Taiwan who require offline navigation and species identification tools.
What does it look like?
Key features
Classifies fungi from photographs using a local model trained on Taiwan and Hong Kong species without cloud connectivity.
Downloads Taiwan-specific map tiles with contours and hillshading for navigation without cellular service.
Fixes the user's path as a reference line and triggers vibration alerts when the user strays 50 meters from the recorded route.
How much does it cost?
The app operates as a non-monetized utility, providing all features without cost or advertising.

Maintenance developmentnew contentUX improvementsShow more...
With only two releases in the last six months, the app operates at a maintenance cadence of approximately one update every 2.5 to 3 months. Development is currently focused on core feature expansion rather than frequent iteration. The latest release represents a significant shift by adding on-device machine learning for plant identification, though the long gap between updates suggests a slow development cycle. The app remains in a maintenance state due to the infrequent release schedule.
