Overview

GripStrength connects to a Jamar Smart dynamometer, plots force live, records three dominant and three non-dominant trials, calculates averages, and keeps a result history.

Now

The simulator flows are built. The next step is end-to-end testing with the physical dynamometer.

Why I'm making it

I wanted six grip trials and their averages to be easy to record without interrupting the test.
