That’s the best I could find. I’m pretty sure that the Papi games were solely developed for the iPhone/iPod Touch so you won’t find them anywhere on the internet.

Did Apple ax it? Sounds like a useful app.

Thanks for the review.

As the developer of touchplot, I need to adress some remarks there.

First of all, of course you can plot more than one graph at one time. You can define three functions (f,g,h) and plot them together, as well as plotting the f derivative if you wish.

Then, ON THE SAME GRAPH, you can draw first terms of an iterative sequence u(n+1)=f(u(n)), one differential equation solution with or without a vector field, contourplots, solution of inequation…

TouchPlot is obviously more complete than grafunc and for that reason demands probably more time to master all of its features (maybe you don’t need all of them right now, but you might need them later on), and you have every right not to like the polish notation used to enter a formula and to prefer grafunc if you wish for that reason.

I am pretty sure though someone who has the need for touchplot features and who takes the trouble to learn using touchplot by doing the tutorials won’t regret it and at one time won’t look back.

Again, a subjective comment is appropriate, but don’t propagate lies about touchplot. You might have bought it and tried it, but you shouldn’t tell you speak from experience when obviously you don’t have much regarding the use of touchplot.

Renouncing using touchplot after a few minutes because at first it looked to you complicated and unnatural is sad. Things don’t come easily in mathematics, and they demand some obstination.

If you have issues with touchplot and want to give it a second try, don’t hesitate to tell me about the difficulties you encounter. I am always willing to provide some support.
