Kinemetron 2.0 is a complete redesign. • New instrument-style Measure screen with a stop-error gauge • Hands-free series: keep firing, every release is detected • Camera health report for a full speed sweep • New light meter with film ISO presets • Improved click detection • Quick setup guide on first launch • Winding and dial clicks are ignored: only real shutter releases count in hands-free series • Camera profiles and history sync between your devices with iCloud • Pro: six alternate app icons • Delete a bad shot, redo a speed, or discard a whole session • A speed needs three agreeing shots: outliers are excluded and replaced, erratic shutters are flagged
Is your 1/30 really 1/30? Kinemetron tests the shutter speeds of film cameras with nothing but your iPhone, and adds a light meter for when you go out shooting. TEST YOUR SHUTTER Fire the shutter next to your iPhone. Kinemetron hears the opening and closing of the shutter and shows the measured time next to the dial setting, with the error in stops. Microphone mode covers slow speeds from 1 second to 1/15 s. HANDS-FREE SERIES Pick a speed and keep firing. Each release is detected on its own, three shots per speed, then Kinemetron moves to the next speed. Finish a sweep and get a health report for the whole camera. FASTER SPEEDS WITH THE IPHONE CAMERA Open the camera back, point the iPhone camera through the shutter at a bright light and measure the light pulse. Camera mode is an experimental estimate for faster speeds. LIGHT METER Reflected light metering with the iPhone camera. Set your film ISO and get aperture and shutter pairs, ready to dial into a camera with no working meter. YOUR CAMERA COLLECTION Keep every SLR, rangefinder, TLR and medium format body in one place, with deviation charts by speed, measurement history and before-and-after service comparison. Camera profiles and history sync between your devices with iCloud. KINEMETRON PRO Three camera profiles are free. One lifetime purchase adds unlimited cameras, PDF health reports, before/after CLA comparison, CSV export and alternate app icons. Measurement accuracy is never locked behind Pro. HONEST LIMITS Kinemetron is a screening tool, not calibrated service equipment. The microphone cannot resolve fast shutters, and camera mode cannot measure curtain travel or exposure evenness. Verify important results with a specialist shutter tester. PRIVATE BY DESIGN All audio and camera frames are analyzed on your device. No account, no tracking, nothing sent to us. Optional iCloud sync stays in your own iCloud account.
