Kestrel

Kestrel tells you which apps on your device are built with Flutter.

Kestrel scans the apps installed on your phone and instantly shows every one built with Google's Flutter framework — along with the Flutter and Dart engine version each app ships and how it was built. Install a new app and it shows up in Kestrel right away.

WHAT KESTREL DOES
• Instantly scans your installed apps, entirely on-device
• Detects Flutter-built apps and shows each one's Flutter/Dart engine version
• Fast, live search across all your apps
• Clean Material 3 design with light and dark themes
• Zero tracking — no account, no ads following you around

PRIVACY FIRST
Everything happens locally on your device. Kestrel never uploads, collects, sells, or shares your list of installed apps or anything derived from it. There is no account and no analytics of your app inventory.

WHO IT'S FOR
Developers, tinkerers, and anyone curious about what's running on their phone — whether you want to see how widely Flutter is used, check an app's engine version, or just explore.

Kestrel needs to read your installed apps to identify which are built with Flutter; this is the app's core purpose, and all analysis stays on your device.
