Intuitive interface.
Large and non-intrusive font.
No embedded context menu to minimize the attention when using the App and think less of how to use it when you don’t use the App.
When you type characters the calculator won’t let you make mistakes.
Pay attention to percentage calculation function:
if number is represented before percentage x%, it are calculated as a=x:100
e. g.: "5%" 0.05=5:100,
if numbers are represented before and after percentage x%y, they are calculated as follows a=y:100*x
e. g.:: "5%89" 4.45=89:100*5.
Other functions are same as in other calculators.
