Open the app and browse the plans in Library. Every plan shows its length, its daily time, its habits and its sources before you start. Pick one and confirm.

The small actions that make up each day of a plan: a wake-up time, a walk, a short breathing exercise. Open one to see its instructions, its time and why it is there.

21 days, for every plan in the library, and the length is shown before you start. You can switch at any time; starting a new plan ends the current one and keeps what you did.

The plan keeps going. Missed habits stay visible in your history and appear in the recap. Nothing resets.

1. Open By Day and go to Settings.
2. Choose Health.
3. Select Apple Health, Health Connect or Oura.
4. Review the categories and approve the ones you want to connect.

Depending on your device and source: sleep, heart rate, HRV, activity, workouts and related readings. Only the categories you approve. You can change device permissions or disconnect a source at any time.

Your account starts private. By Day does not sell health data or use it for advertising. Access is limited to the categories you approve and the features you use. Read the Privacy Policy for the detail.
