ExposureFit

Meter reflected light, compare equivalent settings and keep a clean exposure card—on device, without ads, accounts or subscriptions.

ExposureFit is a focused reflected-light exposure meter for film photographers and manual-camera users.

Point your iPhone or iPad at the scene, tap the area you want to meter, choose your film ISO and aperture, then compare equivalent shutter combinations. Lock the reading and share a compact measurement card.

The app derives an EV100 estimate from on-device camera exposure metadata. It does not save camera frames, request location, create an account or upload readings.

Your first measurement card is free. A single lifetime purchase unlocks unlimited cards. No ads and no subscription.

ExposureFit is an exposure estimator. Verify critical work with a calibrated meter.
