I'm booting the non-math portion of this topic off the list. Interested parties may continue off list. Discussion of smart-phone math apps is welcome. Rich ----- Quoting Michael Kleber <michael.kleber@gmail.com>:

I will never understand why educated, adult persons give up privacy just for fun and 'gaming'

Why do you feel that apps on a phone give up more privacy than any other program running on an internet-attached computer, which surely all of us here use frequently? Phone apps tend to live under some sort of permissions system; anything you run on your home computer has full run of looking through every file on your hard drive.

(However, this is only barely math and only debatably fun, so probably best discussed elsewhere.)
