Is your analogue camera's shutter still accurate — or has it drifted after decades of use?
ShuttR Check measures the real shutter speeds of your analog camera using nothing but your iPhone's camera and a light source. No hardware testers, no sensors to buy, no guesswork — reliably from 8s down to 1/500.
HOW IT WORKS Open your camera's film back, remove the lens, and put a light source behind it. ShuttR Check uses your iPhone's high-speed camera to measure exactly how long each shutter release lets light through, then tells you how far that is from the speed you dialled in — in fractions of a stop.
The app walks you through every step. There is nothing to configure, nothing to interpret: set up, release the shutter, read the result.
RELIABLE FROM 8s TO 1/500 — ShuttR Check measures dependably from 8 seconds down to 1/500.…

“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Not yet tested. No analysis has been run for this app, so there is no version or date to report.
Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
• More stable capture: the measurement now runs with higher priority, so the camera keeps up reliably during a release. • New warning when the light is too bright for a clean reading. • New check on the reference release: if the lamp is too dim or the room isn’t dark enough, the app tells you so you can adjust and retry.

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
