Best App Ever

This has helped me pass Calc one through Calc three. The step by step integral calculator is just amazing. I used to have to google search each integral and hope someone solved it in order to find the steps but with this its like a personalized tutor. Especially helpful in visualizing 3-d plots of functions. A must have for anyone who is pretty much working with any subject that involves numbers. And for $2.99 its a steal
