Twitcher: Bird ID

Identify birds directly on your iPhone and build a personal field journal as you explore birds across all 50 states. Twitcher analyzes each photograph entirely on your device, allowing bird identification to work privately and offline. Confirm your catch, collect unique species, unlock achievement patches, and revisit your sightings through an illustrated nature-journal experience. Designed for birders throughout the United States, Twitcher includes species coverage spanning all 50 states from familiar backyard birds to regional and seasonal species. Features include on-device bird identification, a personal sighting journal, illustrated bird entries, collection progress, achievement patches, and offline operation. No account, ads, or subscription are required.
