Kinemetron vs ShuttR Lamp

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.

A shutter measurement is only as good as the light behind it. ShuttR Lamp turns any spare iPhone or iPad into a steady, uniform white light source — the clean, controlled backdrop that ShuttR Check needs to read your analog camera's shutter speeds accurately. Ambient room light, dimmed bulbs and ordinary lamps flicker or shift in ways that quietly distort a measurement. A screen held at full brightness doesn't just shine brighter — it runs remarkably steady, which is exactly what a shutter test needs. ShuttR Lamp gives you that in one tap. HOW IT WORKS Open ShuttR Lamp on a second device, place it behind the camera you're testing, and point the lens at the screen. Then measure with ShuttR Check on your main phone. The lamp is the light; your other phone is the meter. An old iPad is ideal — a large, even, rock-steady panel — but any spare iPhone or iPad works. WHAT YOU GET A full-screen, pure white light at maximum brightness with one tap Brightness and warmth sliders when you want to fine-tune The screen stays awake — it won't dim or lock mid-measurement Tap anywhere to hide the controls, leaving a clean, uniform field of light A direct link to ShuttR Check when you're ready to measure FREE COMPANION TO SHUTTR CHECK ShuttR Lamp is made to pair with ShuttR Check, the app that measures your analog camera's real shutter speeds using just your iPhone. Use them together for the most reliable readings. PRIVATE BY DESIGN No accounts. No data collection. No internet connection required. The app does nothing but light up your screen. WHO IT'S FOR Anyone testing analog shutter speeds with ShuttR Check Film photographers and camera collectors who want a clean, repeatable light source Anyone who just needs a simple, bright, steady white screen
