What data is required to calculate biological age?

To calculate your biological age on a given day, we require the following information:

• Your sex assigned at birth.
• Your step history for the past 7 days, ensuring that at least 4 of those days include a step history of more than 30 minutes each.
• Optionally, you can provide your heart rate measurement history for the past 7 days.

Additionally, we require you to specify your date of birth. Read Why do you ask users to provide their date of birth? for more details.
