Not really happy with it

Its simple and the key pad is a good idea. But this calculator requires you know your f ratio in millimeters. I can figure that out, but I think a good calculator should not require you provide some of the calculating yourself. Any scope owner would know their mirror size in inches and focal length f ratio, calculating from those figures would be more useful.

Terrible

Don't waste your dollar. If you've updated your phone since 2011, then the app will not even open. Shame on the developer for not keeping the app updated, and shame on Apple for not removing the app from the App Store. If I could I'd rate this app -5 stars.
