Sooner Rater

This application is a percent calculator (Margin/MarkUp/Discount/Increase rate/Decrease rate/TAX). (Same kind calculation as [%][MU][Δ%][+TAX][-TAX][Cost][Sell][Margin] key on calculator) It equips User Interface suitable for Touchscreen. (Direct touch to displayed number works as number input or modification, or switching between result and input.) If you have been calculating percent and using Surface Pro,2in1 PC, etc., it will reduce working time. Please try this application. (It can be controlled from Mouse, TouchPad. But direct feeling fades a little.)
