I guess this shouldn't become an Analyser forum, but on the other hand, it seems one cannot emphasize enough that many would love to see support of Pandas and SciPy in Pythonista.
I made the investment and though the UI is seriously underwhelming, I am quite impressed with Analyser. Besides Python, it contains a pretty rich R environment with lots of popular packages. The main disadvantage is that the editor and the UI overall are rather rudimentary, to put it mildly. Without manually saving it, you may lose your work, for instance. Not an experience you know and like on an iPad.
Nevertheless, for me it is an okay to good offline solution. I certainly wouldn't call it a rip-off.
