iPhone Screenshots


Lightmate is a simple light meter app for photographers. The user interface is designed with clarity in mind.


• Aperture and shutter priority modes
• Multiple EV scales (iOS Settings > Lightmate)
• Back and front camera support


1. Choose the ISO, Aperture (or Shutter) values according to your camera settings.
2. The priority changes automatically to Aperture (or Shutter) mode when you change the Aperture (or Shutter) value.
3. Tap anywhere on the camera's preview screen to measure and update the exposure values.

You can switch the priority mode by just tapping on the Shutter or Aperture values.


You can change the default EV scale individually for Aperture, Shutter Speed or ISO values.

1. Go to the general "iOS Settings"
2. Scroll down until you find "Lightmate"
3. Change to a different EV scale (full stops, 1/2 stops or 1/3 stops)

What’s New

Version 1.0.12

Simple, works!

I like that I can choose where to focus. A couple other meters I tried, I really wasn’t sure what point it was referencing to get its reading, but with this, I know!

What I wish existed was an easier way to access the tutorial after the initial view and perhaps provide a short demo video for beginners.

Simple and accurate

I am new to film photography, so I was very concerned about making sure my photos were properly exposed. I found this app, and tested it out by taking exposure readings with both the app ans my digital camera. This app is completely accurate to a true exposure reading with an actual light meter, so if you’d rather not carry one of those around all the time, this is it.

Nice interface, needs more features

Originally I thought that this app was giving low readings, but it turns out my digital camera was off! My film shots turned out great when using this app. It has a really nice UI, but could use more features. Perhaps something like spot/weighted metering. Overall really good

Hi ellip0t,

We would like to help you get better exposed photos. Could you please share your setup with us (film type, camera) and the light conditions in which you're shooting (outdoor, indoor, landscape, portrait, etc)? Thank you
