【實用財經app】Index Calculator|最夯免費app-綠色工廠好玩App

This is my first application in the market.

This application is very simple and does not do much, I'm using this application in order to learn how the market works.

I wrote this app for a friend of my in order to do fast calculation regrading percentage for stocks.

The first line contain 3 fields. the first field should be a value, the second field should be the lower limit of the percentage, and the third field should be the upper limit of the percentage. when clicking the upper GO button all the percentage value between the lower and the upper will be calculated, and increased and deduct form the value.

the second row does the opposite calculation, when given two numbers it will calculate the percentage needed to be deducted or increased in order to get from one number to the other.
