Expozia is a film light meter for iOS — precise metering, a manual flash calculator, ND compensation, and a logbook for every roll.

Is there a subscription?
No. Expozia is free to download and use. A one-time Pro purchase (no subscription, no auto-renewal) unlocks unlimited frames and rolls, custom ISO/aperture/shutter ranges, the flash calculator, ND filter compensation, and lens focal length presets.
Which iPhones are supported?
iPhone running iOS 17 or later.
Does it work with any film?
Yes. Set your film's ISO and meter as usual; the logbook organizes shots by roll.
