myLightMeter PRO
An app that tells you the right exposure for your camera.
What myLightMeter PRO does
myLightMeter PRO is an exposure meter for iPhone and iPad, made by a solo developer. It tells you the shutter speed, aperture and ISO to use for a scene, with extras for film shooters like reciprocity correction. It costs $4.99 once, with no subscription.
If you shoot with an old film camera that has no working meter, or you just want a second opinion on a tricky scene, this app fills the gap. It does incident and reflected metering, and supports manual and priority modes with a wide range of shutter, aperture and ISO values.
Film photographers get reciprocity correction for long exposures, where film needs more time than the math says. You can group readings into sessions that sync through iCloud and export as PDF, save presets for your gear, and use a hyperfocal distance calculator to keep more of the scene sharp.
It's a paid app at $4.99 with no subscription, and it's still updated in 2026 by its solo developer. It has a high rating on the App Store. If you just want to know how bright a room is, a lux meter is simpler. If you shoot photos, this is the more useful tool.
