Smartboard Calculator isn't your run of the mill Windows Phone calculator app. Inspired by the old school blackboard where you calculator acts like a blackboard where you can scroll around by touch to review all your calculations.
Smartboard Calculator was recently updated to address a few usability and performance issues and tweak the free version. The free version is now a fully-functional, ad-supported version.
This brings Skydrive backup support, Excel export, calculator templates and favorites to the free version. The ad-free version of Smartboard Calculator is currently running $4.99.
You can find Smartboard Calculator Free here and Smartboard Calculator here at the Windows Phone Store.
