The goal of this interface is to simplify, the process of making a group purchase. Each individual invited to the party agrees to pay for x amount. The initial value is an equal share, scrolling up/down adjusts both the percent on the left and the dollar value on the right. Each time a person commits to a certain amount, it is subtracted from the total remaining cost at the top.
This is not an entire app development project. The purpose here is to map a prototype for UX and demonstrate goal behavior.
Code should be written in python, uploaded to a google cloud account.
