Wingbeat: Bird Shutter Speed

Pick the bird (or its size class), pick what it's doing — takeoff, gliding, flight, dive — and Wingbeat reads out the speed that freezes it. Flip to the Technique panel to match how you actually shoot: panning or static, handheld or tripod, freeze the wings or just the body, side-on or head-on, and how large the bird sits in your frame. WHY IT'S DIFFERENT Most advice hands you rules of thumb: "1/2000 for birds in flight." But motion blur is physics — wingtip speed, focal length, pixel pitch, and how strict you are about sharpness. Wingbeat does the arithmetic: • 70+ species profiles — hummingbirds to eagles, with real wingbeat rates and flight speeds • Your gear, your numbers — sensor format, resolution, focal length, stabilization • Sharpness standards — Print, 2px, or 1px targets, so you trade ISO for detail deliberately • Real-world floors — handhold limits, tripod work, gusty-wind allowances • Shutter caps — respects your mechanical limit, uses electronic shutter only if you allow it Every species profile is derived from published flight kinematics — measured wingbeat frequencies and radar-tracked flight speeds — then cross-checked against field practice. BUILT FOR THE FIELD One glance, one big number. Set up your gear once in 60 seconds; after that it's two taps in a hide with cold fingers. No account. No ads. No tracking. Everything runs on your phone. What's New (v1.0) First release: 70+ species profiles, physics-based shutter speed calculator, gear-aware handhold floors and shutter caps.
