Simple, quick and well designed

I shoot on some older cameras with fairly limited settings, and this app is better than any cold shoe meter given its flexibility, quick setup and intuitive use. Highly recommend - and it doesn’t have annoying ads or anything!

Reliable easy simple

I can always count on this app. I don’t use anything else except for maybe my meter when I actually have a battery always comes in clutch.

Great App

Can’t fault it really for a phone based light-meter.
Pretty accurate and great that you can set up for such a range of cameras editing individually.
