⌚ WearableWhiz helps you make sense of your Apple Watch health data. HRV, sleep score, heart rate zones, blood oxygen — your watch tracks all of it. Most people have no idea what it means or what to do with it.

I'm not a doctor or researcher. I'm a regular Apple Watch user who got obsessed with understanding what the numbers actually mean. Everything here is based on personal experience, real wear time, and digging into the sources so you don't have to.
