"This is truly an amazing piece of software for the iPhone that could potentially render all the graphing calculators out-there obsolete! I was very impressed with all the graphing features (2D, 3D, 4D, etc) and the powerful CAS loaded with preprogrammed functions. Use the T variable to create animated plots that graph in space and time! MathStudio is the first calculator to introduce time graphing when it was first released as SpaceTime in 2003 for Pocket PC. Graph equations with speed and ease you never thought were possible! Move, rotate and pinch function, parametric, polar, implicit, contour, spherical, cylindrical, vector fields, fractals and image plots with amazing speed and accuracy. This is the example app for the potential of a device like the iPhone or iPad. They include a really quick tutorial that gets you up and running quickly. The UI is extremely functional and intuitive to use. 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.
