@lechindianer I have a Whoop [whoop.com] wristband. Amongst many other things, it gives a measure of sleep quality (the vertical axis) and required sleep (horizontal axis).
@lechindianer It's one of the best executed wearables I've seen:
- No interface on my wrist to distract me - Can be charged without removing it - Actionable data e.g. if my HRV drops below a certain point, I know I need to take it easy that day.
@jeremycherfas It transmits the data in bursts over BLE to your phone, so in principle you could intercept the raw data. That said, Whoop have a rather simple private API that easy to rev eng and I’m using that to power this chart. // @lechindianer
@jeremycherfas That’s I work at a standing desk all day. Between waking up and dinner, I don’t sit at all. Even then, my heart rate is lower than the average resting heart. // @lechindianer
