VAT calculator+ vs sci.calculator

This app can calculate 20% and 5% VAT. The feature of this app is that a calculation frame is set up separately for each tax rate. For this purpose, you can check the tax-included amount of 20% and 5% at the same time without changing the screen or erasing the entered value. And the total value of each tax-included amount is calculated automatically, so you can check the total amount without any hassle.
