Ratings and reviews

I want to use it and it seems well made. The calculators and everything work well, but this desperately needs the ability to calibrate the light meter. If your phone (like mine) isn't compatible it will just give you very poor shutter speed suggestions. I would love to use it, but I need the ability to calibrate on a known light source.

Checked the readings vs. Minolta Auto Meter IV F ($300 meter), and while I'd never expect an app to be as accurate as a professional meter, the readings I got weren't even close. If I went by this app's readings my photos would be tremendously overexposed. Update: Just to be sure, I double checked readings from a TTL camera meter. Results from the camera meter and Minolta meter were virtually identical. This light meter app was way way off.

it worked great for quite a while, but it just stopped taking readings today. I'm going to delete and readd to see if that helps, but it quit while I was on a shoot, so I just wanted to share my experience. Note: after update I'm still having the same problems. It froze while I was out shooting film, which shortened my day.
