Spot, photograph, collect

Free · Designed for iPad. Not verified for macOS.

How many of the 178 Dutch bird species can you spot? Fully local, no account or tracking. Tweetdex is your personal bird-dex for the Netherlands — spot, photograph, and collect all ~178 bird species found in the Netherlands. Think Pokémon Snap, but with real birds from your own backyard, park, or nature reserve. FEATURES • Clear dashboard — every Dutch bird species in one grid, with a progress bar and filters per category (water birds, birds of prey, songbirds, and more). • Fast search — find the species you spotted instantly, by Dutch or scientific name. • Add a photo — capture your sighting with a photo from your gallery. Date and location are read from the photo automatically, no manual entry needed. • Sighting location on a map — every sighting is plotted on a map, so you always know exactly where you found each bird. • Rich bird info — biometrics (length, wingspan, weight), sound, occurrence, and breeding behaviour per species. Learn as you collect. • Track your progress — stats per category and an overview of your most recent discoveries. PRIVACY FIRST Tweetdex works entirely on your device. No account needed, no cloud storage, no tracking or ads. Your photos and sightings stay yours. Note: species descriptions and biology details are currently in Dutch only. The app interface itself is fully available in English. For beginner birders and seasoned spotters alike: how many of the 178 species can you find?
