Where is money

This program will help save you money. To do this, every time you go to the store and buy the products you record the amount that has been spent. All data is collected and as a result displayed statistics and graphs on what you spend your money the most. The program has categories that is also necessary to specify, here they are: Food, Apartment, services, market, shops, car, wife, etc. You can add new categories and delete unwanted ones.
