Tweetdex is your personal bird-dex — log every species you encounter in the wild, just like Pokémon Snap, but with real Dutch birds.
From first photo to full collection — Tweetdex keeps track per species, per category, and per sighting.
Every Dutch bird species in one grid, with a progress bar and filters per category.
Search by Dutch or scientific name and find the species you spotted right away.
Add your best photo per species — date and location are read from the photo automatically.
See exactly where you spotted each bird, plotted on a map.
Biometrics, sound, occurrence, and breeding behaviour per species — learn as you collect.
Stats per category and an overview of your most recent discoveries.
Tweetdex works entirely on your device. No account, no cloud, no tracking — your data never leaves your phone.
