Lghtmtr is an incredibly simple light meter app to measure the amount of available light to determine the proper exposure for a photo.

Because of its simplicity, Lghtmtr is a great learning tool for students and those new to film photography to understand how exposure, aperture, ISO are interconnected as the app helps the user better visualize these connections.

Take a reading of a scene, and then the initial exposure settings are shown. When you adjust one value, the other values will update. At any time you can lock a value from changing. You can also review the image which your exposure settings are based on.

Clean and simply but...

I love the simple, clean, uncluttered interface. What the app needs is to be able to set some defaults and also to be able to lock two parameters. I shoot film and would like to set ISO to the speed of my film for the whole day and for anytime i use the app after. I also start my shooting at f/16 or f/8 and would like to be able to have the app start there and let me lock it down as well. I love the direction of the app. Just needs a few more tweaks and i will gladly pay for a “pro” or upgraded version.

Functional and Clean

I have tried countless light metering apps and always come back to this one

Being able to snap a photo then tap and view/adjust the type of exposure I am after is so useful, instead of having to just get an overall even exposure I can dial it down to crush the blacks and get more contrast, this has been especially useful for getting night photography that is properly exposed in my opinion.

The ability to set my ISO and lock it is plenty for me as from there I can just turn the aperture dial or the shutter speed dial to work in aperture or shutter priority modes.

Taking a sample photo and working out my exposure from there is a much more pleasant work flow than the typical light meter app experience of constantly updating numbers where ever your phone is point in that exact moment.

Truly able to get everything I need out of this app and it has been consistent and accurate across all of my cameras giving me great results.

A simple gem

I use a beautiful little vintage Olympus Pen F half-frame film camera. I’ve shot film for 50 years, and have a pretty good idea how to eyeball exposures. Having this ultra simple and quick exposure meter, however, is just perfect to confirm my settings. I see a few people here complaining that you can’t lock two metrics at the same time, but honestly for a nice easy-to-use free app, this works just fine. A dandy little freebie.
