This is my very favorite light meter app! I like that it shows me a range of shutter speed/aperture pairs so that I can pick the one that suits the exposure best. It makes using a camera without a built-in meter very simple. Also the interface is clean and pleasant!

I tried to write a long, beaming review, but I hit the char limit. So I'll cut to the chase. Excellent app, almost perfect. Ad-free: developer after my own heart. Thanks much: donate? I'd like to humbly suggest somewhat deeper customizability. I'd love to be able to manually specify min/max apertures & shutter speeds, select/deselect shown films in the picker list, and—the "killer feature"—optionally specify limited apertures & shutter speeds, for those cameras with more granualar controls.

Thank you for your feedback! Specifying min/max values will be available in the next big release. If you are a GitHub user, you can create a feature request for selecting films and other features via "Report an issue" setting in the app. If not, please write me and email and tell more about "limited apertures & shutter speeds". Thanks!

Love the app, very useful for someone who doesn't own a light meter. I checked against my d7100, seems to be pretty accurate. I do wish there was a way of resizing the parts on the screen, as the camera window is a little small for accurately placing the spot in spot metering.
