Separate demand from paid growth

Store rankings and revenue estimates describe market context. They do not establish ad spend, conversions or ROAS.

Cute, I guess it gets the job done. Not for iPad.

It says it's for iPad but it's not (it stretches the screen). The tones are annoying when you get an answer wrong, perhaps that's intended. There are misspellings in game. Overall it's ok, so far.
