*Calculator Toolbox* is... well... a calculator app for your Windows Phone. And to call it a calculator app is a mild understatement.

Beyond doing your basic arithmetic *Calculator Toolbox* throws in six categories that hold thirty four calculators. There are two versions of *Calculator Toolbox* for you to choose from. A freebie version that has ads and an ad free version that is running $.99. If you need more than your basic calculator, *Calculator Toolbox* is worth checking out.

When you first launch* Calculator Toolbox*, you will quickly realize this isn't your typical calculator app. *Calculator Toolbox *makes use of the Windows Phone metro design by laying out all the tools in a clean, attractive panoramic style.

You have a page dedicated to your favorite calculators, a page listing the six categories of calculators, a page listing all the converters available (twelve in all), and an about page for the developer.

Within each category you'll find a listing (with description) for each calculator. Asides from your basic calculator, Calculator Toolbox has the follow additional calculators available.

Once you find your calculator of choice, you'll have a variety of screens (dependent on the calculation) where you enter all your variables and hit the calculate button.

*Calculator Toolbox *has Live Tile support for the Tip, Discount, BMI, Age, DTI Ratio, VAT/Sales Tax, Mortgage, Auto Loan and Auto Lease calculators.

When all the variables are factored, the sum value of the *Calculator Toolbox* isn't too shabby. The entire app makes the abacus pale in comparison.
