Bionny Age

What do your daily habits add up to over time? Bionny Age is an estimate based on your activity, resting heart rate and sleep, compared with the results of large population studies.

Why Bionny Age is worth tracking

Large studies that followed thousands of people over many years show that more daily steps ¹, meeting the activity guidelines ², a lower resting heart rate ³, 7 to 9 hours of sleep ⁴ and regular sleep times ⁵ are each linked to better long-term health.

Bionny uses these results to turn your habits into years: healthier habits may give you a Bionny Age below your actual age, while less healthy habits may push it higher. The calculation was designed by our data engineers, based on published research, and is deliberately cautious. Bionny Age is a wellness indicator: it isn’t a biological age and doesn’t measure the health of your organs.

Bionny Age questions

Why doesn’t my Bionny Age change every day?

Because it reflects your habits over weeks, not a single day. It’s updated every two weeks.

Do I need to wear the band at night to get my Bionny Age?

Yes. Your resting heart rate and sleep are part of the calculation, and both are measured overnight. Without enough nights, your Bionny Age can’t be calculated. That’s normal. If you stop wearing the band at night for a while, your last value remains visible until you resume overnight tracking.

How can I lower my Bionny Age?

Walk more, add some activity that raises your heart rate, and keep enough, regular sleep. Changes show up over a few weeks.

Who can get a Bionny Age?

Bionny Age is available from 18 years old.
