Sooner Rater app for iPhone and iPad

This application is a % calculator(Margin/MarkUp/Discount/Increase rate/Decrease rate/TAX). (same kind calculation as [%][MU][Cost][Sell][Margin][+TAX][-TAX][Δ%] keys on calculator)
Repeating a similar calculation is sometimes necessary. Full number input again and again is a nuisance. Dont you think its better if the calculation result comes only by different point correction? This application fulfills it.

Not all calculation finishes with getting the result. You often have the demand such as follows.
・To get results when the input is different. And the results of more various inputs.
・To get the input of the adjusted result.
This application watches a touch action to display number itself and does numerical value correction or input.
It makes simpler and easier the operation (correction, recomputation) like above cases.
