TL;DR: Here’s a transparency reporting tracker for 12 health/fitness wearable brands. Introduction I’ve worn a Garmin GPS device for well over a decade. I’ve logged thousands of activities–runs, rides, swims (ugh), walks, hikes…you name it. If I’ve moved, it’s probably been logged. It’s fascinating to look back at this data periodically to see how my fitness has changed over time, and I love being able to monitor progress toward big goals.
