Easy way to entertain and challenge the kids and some times helps the adults to focus and regain some attention span. Simple and cool interface. I had this in my windows mobile and glad they have it in iPhone.

Unsurpassed

This is by far the best calculator (if you can call it that) app on the iTunes app store (as of the beginning of 2009)- it has a featureset comparable to that of an advanced graphing calculator, like a TI-89, but with the benefit of a touch-screen interface and full-color graphics (which are especially nice for 3D plotting). SpaceTime also performs both numeric and symbolic algebra and calculus (including some advanced functions) and supports scripting. If you've used software like Maple or Mathematica, SpaceTime works in a similar function- not quite as feature-rich, but far more than you might expect from a handheld device.

Amazing!!!

This app is the best food app ever. It has never froze on me and it is so informational. It helps my fiance and I keep healthy and buy the right foods.

Wonderful!

It's like having a simple wolfram alpha you can use offline!

A great game! Copy the color pattern in the sample circle by turning the rings. There's one black empty space. You push the arc you want to move onto into the empty space then turn the rings to reposition it. It's like one of those number 15 puzzle games only with a circle, arcs and pretty colors.

Awesome!!!

Does just about everything my TI-84 Plus but quicker and much easier to manipulate the graphs. It loads instantly and the 3D function is awesome for higher level math classes (I'm in Calc 3 now and it's already come in hand!)
