How it works

A daily ritual, not another dashboard.

01

Check in

Take a quiet one-minute check-in. No scorecard—just a little context for your day.

02

Connect what you want

Optionally connect Apple Health and other signals when you want a richer picture.

03

Ask Kuro

Ask why you feel tired, when you focus best, or what habits shape your strongest days.

Private by design

Your signals stay yours.

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.
