Just named by Apple as 1 of  10 Apps That WOW and FREE  – MyScript Calculator is an amazing app. It performs mathematical operations literally by hand! You write the problem … it solves the problem! The app is very simple to use. Just write the mathematical equation on the screen. MyScript technology converts the symbols and numbers to digital text and delivers the answers. It supports the following operations: basic operations (+, -, x, ÷, +/‒, 1/x), additional operations ( %, √, x!, |x|), powers/exponentials (ℯx, xy , x2), trigonometry, and more. Very cool!! MyScript Calculator also won the Mobile App Showdown at CES 2013!!
