Butterfly Atlas App Overview
Last updated: 2026-10-31
Applies to Butterfly Atlas (com.butterflydex.app). Operated by WS App Studio.
Explore 120 butterflies with photographs and teaching illustrations. Read names and features in Korean, English, Japanese and Spanish. Search, compare two butterflies, answer quizzes, collect cards, save favorites and review missed answers. The 115 photographs distinguish preserved specimens and fossils; five entries use teaching illustrations. Unverified sizes are marked as under review instead of displaying estimates.
The atlas and photographs work offline. Advertising requires an internet connection.
Watch wild butterflies without catching or touching them.
