Great upgrade!!!!

LOL- all you have to do to get help from the developer is touch the calculator ? key twice. Or just select the “App Support” button in the AppStore (next to the "Write a Review" button) and talk to the developer directly. This developer has amazing tech support and responds very rapidly. If you touch the ? key and then another key a help page with examples of how to use the key is displayed. All the menu functions have a circled i icon. When you touch the icon, a help page is displayed that demonstrates how to use the function.

You don’t need a TRACE button anymore- just go to the GRAPH screen and touch the graph you want to trace with your finger. The Zoom and Calc functions are conveniently located at the bottom of the graph view instead of the keyboard- great shortcut!

This is so much better than anything else on the app store- it has color, it has touch interface for everything, it has a periodic table to kill for and it is blazing fast for graphing FULL SCREEN on iPhone and iPad. And now the developer has added split screen and slide over multitasking for the iPad! All for a small fraction of the cost of a TI.
