About
One notebook for bugs, butterflies and moths.
Switch between two volumes, Insects and Butterflies & Moths, and look up names from your own photos. Everything runs on your device, so photos are never sent anywhere and it works without a connection.
PICK A VOLUME, THEN SHOOT
- Choose a volume on the shelf; the guide, photo ID and quiz follow it
- The AI suggests candidate names from a camera or album photo (only a guide, never a verdict)
- Tap the one you think is right to save it as a record
TWO VOLUMES
- Insects: 230 species, from beetles and dragonflies to cicadas and bees
- Butterflies & Moths: 76 species, with appearance tips and family notes
HOW TO BUY
- Browsing the guide cards and keeping records are free. Photo ID is limited to 3 a day (unlimited for the first 7 days)
- One purchase unlocks unlimited photo ID for both Insects and Butterflies & Moths
- The one-time purchase also opens unlimited quiz, a map of your finds, CSV export of your records, and photo tips and observation hints (no ads)
- The all-volumes pack opens every land volume, including ones added later
- Not a subscription. On a new device, use Restore purchase
SAFETY
Avoid touching unfamiliar insects with bare hands. AI results and guide contents are estimates; do not use them to judge whether an insect is dangerous.
