Biotadex, a nature collection game for people who go looking
Biotadex presents a real-world nature-collecting game that identifies photographed plants, animals, fungi, and other living things, then turns the finds into points, stickers, postcards, and community-checked records.
- For
- Nature watchers and outdoor collectors
- Worth noticing
- Uncertain identifications can be held for community review, with three confirmations releasing the score and three flags reversing it.
Field notes
The proposed scoring system combines species rarity with environmental timing: first frost and first snow are listed at 4×, while low tide and night shift are listed at 2×. A scan stores the selected species alongside the photograph, location, and time, and lower-confidence results can enter a community review process. The homepage also describes a bilingual spoken layer, with facts drawn from the species record.
