In Which We Get Ourselves an App

Reprise: the "200/50" Exercise

This week I got an email from a very nice and apparently quite gifted person named Mike Schutte, who told me that he had invented an app to assist in the 200/50 exercise described in Appendix B of A Swim in a Pond in the Rain.

I tried it, it worked, thirty minutes flew by as I kept trying it.
