In modern supermarkets, pre-packaged goods weighing on the label are sometimes sold the price for this weighted product and its weight. Therefore it can be difficult to understand how much this product really worth it. For comparison with another variety. Or to understand which product is more profitable to buy.

A simple example - which is more advantageous - a bank of instant coffee 75g for 145 or a bank 95g for 260? The goods are the same, only the packaging is different. There are three or four and five or six different options of the same goods. Of course, you can run any conventional calculator and calculate the cost of each.
All the same does our application. But it already has a formula for this calculation and automated part of the action. It is enough to begin to enter the numbers of price and weight, as in the top field appears the finished total.
In addition, you can enter a note and save this information on the screen, which will clearly help determine with a choice of goods and buy it at the best price.
