Not super related, but my Physical Therapist was super impressed that my phone could show my left/right imbalance ("walking asymmetry" in iOS health). It's been a pretty good measure of my progress in recovery post-surgery. She had no idea this even existed, and then had a second patient point it out to her just a week or two later. I imagine Android has similar features (or 3rd party apps can be installed to do so).
