Calculator³ for Windows Phone has been updated to take full advantage of new functionality on new hardware. The app now supports all screen resolutions, as well as featuring multiple Live Tile sizes. If you're not familiar with the app, Calculator³ is a simple calculator that sports five modes: Basic, Scientific, Programmer, Currency Converter, and Unit Converter.
If the Windows Phone 8 support wasn't enough, Live Tile size support has been included in the Windows Phone 7.8 version of the app. The developer has contacted us to announce that the paid version of Calculator³ will be free through next week - even more reason to pick it up from the store.
