Don't buy.

Waste of money, I tried to look up APPL app says can't compute. Aren't you guys supposed to be math geniuses.

I would like a refund! How can I get my $5 back?

This app may boast some neat analyses and cool charts, but since the formidable "supercomputers" behind it can't pull data for widely traded ETFs like XLF and EEM, it's essentially useless to me. A missed opportunity and a blot on Wolfram's good name.
