About this app

I was hesitant to get this app but I'm glad I did. It is just like the $60 calculator you buy only you have a settings and preferences menu and you can take screenshots of your calculations instead of having to write it all down on a block of wood

I've been using this app a long time. It's exactly the same as the calculators our company uses and I never misplace it now. Perfect for home renovations and an all in one calculator for every day use! Well worth the cost and I have always been able to reinstall with new phones.

Anybody worth the sawdust in their shorts knows the math the old fashion way.... But who would not want to use yet another tool in the bag to lighten the daily load! Easy calculations and conversions just part of the everyday roll out now that its inside my phone!
