Ratings and reviews

doesn't calculate for you. I input the lens details I'm using and its supposed to tell me how much extra magnification I get or how many steps I'll need for stacking. It just displays 1 step.

was a handy tool, seems to have updated and now it's broken, can't type in numbers into ratio fields without keyboard covering it, it entering all sorts. if the free version worked properly I'd consider buying. But since that's broken and full of ads now I'm going to look for something else.

This app is not a camera app. This app is a calculator app for people who are serious about doing macro shots and have at least some sort of background in photography. If you are trying to use your $1200 iPhone 16XL 7G LTE phone to simply get close to an object and take a photo of it, then this is the wrong app for you. I have made many different types of calculators and this app is incredibly helpful for people who use these calculations on a regular basis. Use 'Open Camera' for phone macros.
