This is an unique mobile app, showing you how much money you can save by memorizing your purchases! First, you enter the details of the product, that you have just bought: name, photo, price, date of purchase. Next, as soon as you sell that particular product, you again – enter the details, especially the price, that you sold this stuff for. And automatically you can see how much money you have earned (or lost) on this whole transaction! The app records all your purchases and counts your actual cost of buy-sell transactions. It is simple, it is efficient, it is time-and-money-saver!
