Thank you for trying Project Kestrel!
Please share your thoughts using the Feedback button within the app to help me improve the experience for all bird photographers.
From the developer
Project Kestrel is a one-person project, built over years of weekends because I wanted these tools for my own bird photography. The app is free and open source, and always will be; my only sources of income are your donations and your subscriptions to Cloud Compute. Read my story →
Windows
Note: The traditional Windows installer will be deprecated after v(Dusky Grouse). Read why →
macOS
Purchase from Apple App Store
$10, with automatic updates — a way to support development, not a different app. Why it's paid →
Free Direct Downloads
Note: Intel builds are provided release by release and may stop at any time as Apple winds down Intel support. Apple Silicon is the primary macOS build.
Here for an update? Updates are free and always will be. If Kestrel is useful to you, a donation goes toward the running costs and the next release.
