This app can be used to calculate the amount that the user has to pay in advance when going shopping in advance, and let the user be aware of how much money he/she saved by keeping track of what he/she is buying, thus the user can remove items "wanted" versus items "in need".
I will appreciate any comments, or functions that you want to be included in next version of the app.
Just a sample of what I can do with Objective-C and iOS.
