10Calc – a sleek, feature rich Windows Phone calculator

There is a host of calculator apps available in the Windows Phone Store for those who need to go beyond the native calculator that is pre-installed on our phones. 10Calc is a fairly recent addition to the calculator family and hopes that its sleek appearance, fast performance and a library of calculator styles will appeal to most.

Truth be told, as long as a calculator can add, subtract, multiply and divide I'm a happy camper. But many will need a bit more horsepower out of their calculators and in the short time I have spent exploring 10Calc, it comes across as a worthy Windows Phone app to consider.

10Calc's appearance is very clean with the type of calculator displayed in the upper left corner of the screen and your keypad consuming the bottom portion of the screen. The core interface for 10Calc is equally as clean in that you slide to the left to reveal the app's menu and slide to the right to view your calculation history.


The menu offers options to toggle between the various calculators, access the settings and view the About screen. 10Calc's library of calculators includes:

  • Simple Calculator
  • Scientific Calculator
  • Programmer's Calculator
  • Unit Converter
  • Unorthodox Calculator: This includes a base converter, bill splitter, tip calculator, date-time calculator and Day on the Date Converter

Should anything other than the history become available by swiping to the right, 10Calc will alert you of the differences. For example, to set the units of conversion, just swipe to the right to view the unit listings.


Settings are somewhat minimal and include:

  • Accuracy Level: Super Accurate, Scientific (8 places) and Student (5 places)
  • Font Size: Small, Normal and Big (only affects the input display and not the buttons)
  • Theme: Default, Phone Accent, White
  • Start-up Calculator: Choose which calculator will appear when the app launches
  • Pin Live Tile (Transparent)

There is a Gold and Silver Theme available with the Premium version of 10Calc, which will run you $1.29 via in-app purchase. The Premium version will also remove the ad support.

10Calc does have copy support where you can tap on the calculated sum and copy it to your Windows Phone clipboard. There is a bug with this feature in that when you are using the big font, you can highlight the figure, but you cannot copy it.

I did like the viewable history, but the copy feature doesn't extend to the history view. You can swipe between the calculator view and history view without losing any of your work, but I think it could be useful to be able to copy from your history. If for anything, to help make it easier to copy sums from the history and import them into the active calculator.

Overall Impression

The more I used 10Calc, the more the Windows Phone app grew on me. My calculator use is limited, but I can see the appeal 10Calc should have with those who need a beefier calculator. The interface is clean and optimized for one-handed use and the selection of calculator styles is respectable.

All in all, if you are in the market for a Windows Phone calculator that goes beyond the native app, 10Calc is worth trying. It is a free, ad-supported app with the option to remove the ad-support through a $1.29 in-app purchase. 10Calc is currently rated at 4 Stars, which is about right for this Windows Phone app. If you try 10Calc, let us know what you think of things in the comments below.
