It provides features comparable to TI calculators but with a modern and intuitive interface. "I've been waiting for a program like this a long time on my iPhone or iPad, and somehow never found MathStudio until now. This is a phenomenal engineering application for the student or professional. It does it all... Solving equations, integrating, calculating derivatives, and graphing. I had a TI-92 calculator back in my college days that I used for years and dearly loved and this app blows it out of the water. The UI is extremely functional and intuitive to use.
