Features
Read full description

Your bird life list may already be hiding in your camera roll. Feather Trove privately searches the photo library you already have, finds likely bird photos, and suggests species on your iPhone. No choosing photos one at a time. No uploading them to an identification server. With Feather Trove, you can: • Scan your photo library for likely bird photos • Review on-device species suggestions and make the final call • Build a personal life list from years of forgotten sightings • Explore where your bird photos were taken on a private map • Group sightings into bird walks • Confirm, correct, or remove uncertain matches • Create and share polished bird cards • Export your life list as a CSV file Bird detection and species suggestions run on device. Photo dates and locations can refine suggestions locally when available. Original images remain under Apple Photos permissions, and Feather Trove does not upload your photos. Species suggestions may be incorrect and should be reviewed. Subscription note: Most Feather Trove functionality requires an active subscription. Without a subscription, you can view only four summary counts: detected species, photos, mapped photos, and photos needing human review when the classifier cannot decide between two likely bird species. Feather Trove offers weekly and annual auto-renewable subscriptions. Payment begins when you confirm your purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel in your App Store account settings.
