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. Winner of the Mobile App Showdown at CES 2013, MyScript Calculator has been redesigned to work with iOS7. The update also allows automatic calculation to be disabled and replaced by a “calculate” button. Love this app – numbers have to be written somewhat legibly for it to work. 🙂
