1. I don't need a feature packed calculator for engineering and/or advanced mathematical things, just an easy way to add, subtract feet and inches.
2. I don't mind paying for quality and this is nice.I needed a better way to convert feet-inches to decimal inches, to help me with my hobby of taking old home floor plans and creating 3D virtual models, from them.
3. Used the free version for the last year, just upgraded to paid because I wanted to support the developer for a good, simple app that saves me time.
4. The previous technique was either to convert feet and inches to decimal inches, for faster entry, or take 5 keystrokes to enter feet first then inches.
5. Or maybe list inches only between the return value and decimal value.I'm often dealing with one measurement being fractional, and one being decimal.
6. And if that is impossible, maybe a button that would toggle the return value from feet and inches to inches.
7. Like others, I purchased the full version, not because I actually needed an ad free version, but because I think good app developers deserve to be properly compensated for their work.
8. After figuring out how to set the secondary measurement display to inches, I was set using this app, it is perfect for what I needed to do.
9. So it only allows me to convert feet to inches, but not inches to cm, for example.
10. Also this app isn't forgotten like so many other, the developer is always updating,I was looking for an app for those times when I didn't have my construction master calculator with me.
11. Paid the $6 to go ad free if only to support the developer.I use this app for work (structural engineer).
