Ratings and reviews

Never liked the calculator that came with the phone. Found another app that I liked but it seems that updates over time began to make the app hang up as well as the phone. Stumbled on to this one by accident and I love it. It's smooth and the several different themes means there is one you will probably like. It is both a simple calculator and a trigonometry calculator. I couldn't ask for more.

All in one calculator was best many features removed in new version

Probably the most convenient and comprehensive conversion collection in a small format. The only way I could think of to improve it be including some conversions (yards needed for concrete) and plug in formulae. Lb/A = Kg/Ha, Gal/Acre = L/Ha, Oz/SqFt = Gm/SqDecM examples Adding a dedicated reciprocal key would be very handy.
