You are at the super market, and then you see many bags of sugars (of the same brand!) 400gr, 900gr, 2000gr and you think, the bigger, the best unit/value. Well, most times that kind of thinking is wrong! With this app you can tell which one is the best unit/value, you only input the price and the number of units of two of them, and it tells you which one is the better unit/value, then you compare that one with the others to find the best one!
