    Compare grocery prices using Rainbow Compare. Rainbow Compare automatically calculates and compares unit prices of the products that you're interested then visualizes the comparison result for you to make a more informed, frugal buying decision.

    Rainbow Compare - save more on groceries

    Please check out my new free app Rainbow Compare. It is an app designed for all of you smart shoppers in mind.

    If you're a regular grocery shopper, this app will be of great help to you.
    Imagine yourself in the aisle of supermarket shopping for beverages and you come across the following products:

    1) Beer, $ 1.25 / 12 fl oz
    2) Milk, $ 2.45 / 1L
    3) Orange Juice, $ 2.65 / 1250 mL
    4) Soy Milk, $ 1.50 / 850 mL

    And you're really open for all as long as it saves money.. so which one is the cheapest?
    This is where Rainbow Compare comes in, just put in the price, quantity, and unit... and voila!
    The result is presented to you, visualized:

    Now you can make a more informed decision. Not a grocery person? No problem, introduce this app to somebody who is.
    I'm sure they'll benefit from this free little app.

    Other features include
    1) Compare up to 4 products at the same time
    2) Real-time unit price calculation with optimized precision
    3) Auto unit conversion

    Also, Rainbow Compare is free.. so you're saving while you're saving.
