App Description

Designed by a photographer for photographers, focused on RELIABILITY and PRECISION for digital and analog photography.

• Extended sensibility as low as -2/-4EV (dark scenes)

• Two different convenient interface designs.

• Incident and reflected light metering modes.

• Save exposure data.

• f/Tools connection.

• Independent calibration for the two metering modes.

• Independent selection of aperture, speed, ISO and exposure compensation with 1/3 resolution. From 4 minutes to 1/8000 sec., aperture from 1.0 to 512 and iso from 3 to 6400.

• Automatic priority for aperture or speed. (Automatic Av and Tv modes).

• Automatic ISO or locked ISO options.

• Spot metering and zoomed camera view.

• Maximum aperture limited by the selected lens.

• Calculate the average of any number of measurements you want.

• Read the exposure data of any photo from the gallery.

• Calculate hyperfocal distance for 5 memorized lenses. Which also blocks maximum aperture.

• Memory for 5 lenses with maximum aperture, focal length and film/sensor size for calculating hyperfocal distance and aperture.

• Hyperfocal distance also for infrared light. (IR button)

• Exposure value EV on an analog scale or right up front.

• Two LED indicators show whether the measurement is unreliable due to lack of light in the scene, or if we have under 30% battery left.

• On 3.5 " displays preset lens buttons tilting the device or tapping at the bottom.

• Be advised that accurate incident light reading needs a diffuser attached to the front camera. Without the diffuser still can be used but think about it, it will be a reflected reading taken with the front camera.

I'm an independent photographer/designer/developer and am very grateful for your support. Trying to do the best lightmeter app ever, a lot more to come. You can ask for any improvement and I'll be happy to help. This app is constantly reviewed and improved because it is my tool, if you have any questions or suggestions feel free to contact me by email at

Thank you!

I don’t ever rate apps but as a film photographer I feel as if I have to help out this independent app developer. I do not own an actual light meter but this app gives me the proper exposure settings for 1/20th of the cost. I will eventually go out and spend the money on a light meter but until then, this app suits my needs 100%. I shoot with a Mamiya RB67 and some Canon and Olympus 35mm SLRs and this app never fails any of the cameras.

Not for plants

Might be great for photographers, but can’t seem to get a basic foot candle reading for plants. Wasted my $$.

Very Accurate

This is a great app, it’s right on. I’ve measured it against multiple light meters, including the excellent meter in a new leica MP and it’s great. There are a few features I wish it had, I wish I could save the measurements, lens and aperture/shutter and phone photo it’s taking, so I don’t have to keep a notebook of shots as well. I also wish it had frame lines for the lens it’s got as a preset. But as a simple light meter, it’s excellent. I stopped carrying an additional meter after testing it.

I was a little Leary when I first found this app. I wondered how a camera phone and software could accurately measure light. After all, physical light meters are quite expensive. However after reading the reviews and looking at just a few dollars for the app, I decided to pull the shutter! I am not disappointed!! As soon as it was downloaded, I set up three different product shots in my studio. I measured the different lighting using Led always-on lights and then switched out to 2 strobes. The accuracy of this app blew me away! Out of three setups and several images captured, None were off the mark. Thank you for creating this app. I am so glad I found it!

Well done!

This is the most accurate iPhone light meter I have used and the two interfaces are very well done.
