Pio listens to the birds around you and tells you which species are singing. Tap to record a nearby bird, and Pio identifies it from its song, with a photo and a few facts. No signal out in the field? No problem. Pio saves your recordings and automatically identifies them the moment you return online. What you can do: • Identify birds by their song or call • Build a collection of every bird you've heard • See them on your own map, pinned where you first heard each one • Earn badges as your collection grows • Share each bird as a beautiful card • Record offline anywhere, identified automatically once you're back online • Available in English, Portuguese, and Spanish. Step outside, listen, and discover who's singing. Pio is free, with no ads and no accounts. If you like the project, buy me a coffee! https://buymeacoffee.com/piobirdsoundidentifier
