Sadly, this app appears to be abandonware. I paid for the upgrade but the ads still appear. I’ll request a refund from Apple. Too bad, because the app has a lot of potential.

After trying on the order of 15 to 20 different apps, I have surmised that this is a tool I will stick with. Depth of field and hyperfocal distance are critically important in most photographs. When he comes to using a calculator, these apps can be somewhat annoying to use. After all who takes out their phone or what have you to check these kind of details. We should be checking, or know the answers to these questions. What is my current depth of field? What is my hope hyperfocal distance? Well now you can take all of five seconds to answer those questions.
