About this app

I've made this app for real old school photographers or advanced amateurs shooting analog photography. For the price of a soda you will support hundreds of hours of work.

LightMeter's reflected light meter only works with devices that are able to save exposure to exif. Incident light meter usually works on any device but...

Be advised that the precission and quality of this and all phone light meters is limited by the device itself. I recommend using the reflected light option, the precission can be really good.

Features:

-ISO range from 3 to 6400.
-Incident light metering (needs light sensor)
-Reflected light metering (needs camera, only a few are compatible)
-Low light alert.
-Camera can be muted. (not in all countries)
-Exif and sensor info displayed on screen as an option.
-Calibration.
-Vibration on measure/hold.
-Incident light reading can be held.
-Alternative ISO selector.
-State and ISO recall on resume.
-Spot measure if camera has zoom.
-Support for all screens, including extra high resolution.

Thanks for your support

I shot an entire vacation using this app. 8 rolls of film with essentially very basic entry level knowledge of film photography. In terms of exposure, almost all photos turned out looking great. I tried using other apps and they just weren't as intuitive as this one. I like how simple this app is and for someone who has probably bought less than 10 apps ever, this is one that I am happy I paid for.

Excellent! Nice to have meter with an intuitive, analog readout. I love the simple calculator dial of my Weston 737, and this works just as well. Unfortunately the settings tab is placed where I can't get to it: if I try to touch it, phone settings come down instead of app settings. I would LOVE to see continuous reading in reflected mode. Perhaps this is a little ambitious, but that would make this my favorite metering app by a huge margin.

Off by three stops. Had this app for a few years now. It worked great on my Pixel 2. However, when I upgraded my phone to the Pixel 6, the app is now off by 3 stops. If I'm metering for 400 speed film, I have to set the ISO on the app to 50 to get a proper exposure. Even though it's 3 stops off, because of it's simplicity, this is still my goto light meter app.
