Silly offering

You download. You try to see how your particulars (age, sex, etc) impact this app’s version of analytics. You’ll never know unless you blindly sub at $20/year. Dev, when you can’t figure out the raw basics of a test drive, no way in Hades would I trust you to figure out the tricky stuff. Deleted with dev’s I.D. added to my permanent “no!” List.
