Looking for Graphing Calculator App

[rock294]

Does anyone know any good graphing calculator App which can replace the TI-83 or 89 ? :D I found one which is called Space Time. But it's quite expensive compared to other application.

What function do you need? There are quite a few..
I had one that just made graphs, it was fine for that but a bit limited (ie no finding x by setting y=0) but it was free.. I'd just stick to your TI., as if you need it in exams/tests your iPhone won't be aloud in :(

There's one called Graphing Calculator which just draws graphs and is free: http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=289940142&mt=8

HiCalc Lite is fairly full featured http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=294419234&mt=8 and it seems there is a sale on the paid version (from memory it was a little pricey for my liking which probably means it was 4-5 $AU) http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewArtist?id=286038741 It pretty much does integrals and finds derivatives but only outputs in numerical form (so it finds the derivative at a point or does definite integrals).

Those two with the built in scientific calc don't quite replace my TI83+ but it's good for not-exams and quick answers. There are probably pricier apps available that do more, but I haven't really looked into it.
