A great start!
This is a nice little app. I’m using Apple Fitness to track workouts (recorded in a few different apps) and needed a single place to track shoe mileage. This seems to fit the bill. The only downside is that this requires manually entering (and remembering to enter) every workout. It’d be great if it could pull workouts from Apple Fitness and create draft entries that I can then associate with a shoe. That way I can go tag a bunch at once and know I’m not missing any.
