Went for a walk, came home, and decided that my next personal coding project is going to be a terminal-based fitness tracker in python. Just something to log steps, bike riding distance, and other move minutes I might get in during the day. With really quick input on the command line. Like "fit 1500 steps" logs 1500 steps and "fit 7.5 m" logs a bike ride. Which then generates data I can turn into a Jupyter notebook to set realistic goals for improvement. Super simple. And I own my data.
