Have you ever thought about how much money you could save if you consider the cost of products not by packaging but by weight? Imagine that 2 seemingly almost identical product packages in a store can have completely different prices. Install the Correct Economy application and you can quickly calculate the cost of any product in grams, milliliters or liters. Let’s say you have a large bottle of water and it contains 2.9 liters and the price suits you, but there is a similar bottle with 2.7 liters, but with a different price, and for this, our application will help you quickly calculate the cost of 100 milliliters of water and find out how much water will cost you cheaper.
