Ruta MeterFilm light meter for iPhone
See the light across the whole frame.

Simple to use
A complete field workflow.
Ruta Meter begins as a practical meter. The film and long-exposure tools are there when the scene needs more careful planning.
Read more than one spot
See exposure values across the image so one average reading does not hide a bright sky or a dark foreground.
Freeze and compare
Hold the scene, inspect an area and mark important details before the light or composition changes.
Work with your film
Choose a film stock and working EI, then use its exposure range as a guide for shadows and highlights.
Correct and time
Add an ND filter, apply supported film reciprocity data and run the timer without leaving the app.
Inside the app
Five screens. One clear story.
These are the same real Ruta Meter screens prepared for the App Store. Swipe sideways on a phone to see all five.
Clear pricing
