Perfect for High School

This app saved me from having to buy an over priced graphing calculator. I would recommend this app to any one who needs to purchase a TI-83 calculator for school. This app performs all the same fictions for only 2.99 rather than 200 dollars!! The trace function is particularly useful as it provides exact values. This app is truly amazing!! :)
