Lifer

什么是 Lifer？

Lifer turns birdwatching into a collecting game. Identify birds by sound or camera, catch them as beautiful species cards, build your Aviary and Life List, join Birding Parties with friends, create private Flocks, track walks, chase streaks, milestones, rare finds, and Prismwing cards. Built for birders who want ID, logging, and social discovery to feel more playful and rewarding.
