Customer Reviews

Works well

I like that the flip takes it from a simple calculator to more of a scientific calculator.

It's a little laggy on my old iPhone.

Great free app but paid to support developer

The free version did everything I needed. It is such a great little app that I felt obliged to buy the upgrade to support this app maker. Hey bonus: No adds but they weren't that intrusive anyway! Definitely a must have for your device.
