this is relatively new software and it is very interesting based on first impression. It is a free PC program with the usual “pro” upgrade. The cell phone app is 2.99
It is a combination search engine and computation program. It can do a mathematical analysis of almost anything. Physics, Astronomy, financial, it is all there.
As a demonstration it will do an analysis of your FB profile. If you like graphs, stats etc, you will be impressed. I was.
Give it a look and give me your opinions pro or con.
