The Human Observatory

How it works
Take a quiet one-minute check-in. No scorecard—just a little context for your day.
Optionally connect Apple Health and other signals when you want a richer picture.
Ask why you feel tired, when you focus best, or what habits shape your strongest days.
Private by design
Kuro is designed around anonymous contribution, explicit integrations, and controls that make it obvious what you are sharing. Humanity-wide findings should never require giving up yourself.
