Guides
These guides explain the ideas behind the numbers Beebsi shows you, without the jargon. If you've ever wondered what a good HRV actually is, how a recovery score gets built, or what biological age is supposed to mean, start here.
Beebsi reads the data your watch records through Apple Health and turns it into recovery, sleep and vitality readings. It works with any smartwatch or band that syncs to Apple Health, including Apple Watch, Garmin, Fitbit and Oura, and needs an iPhone. The pages below explain what each reading means and how to use it.

What heart rate variability tells you about recovery, why it's measured in milliseconds, and how Beebsi reads it from your watch.
How your recovery score works
What goes into a daily recovery score and how to use the number to decide whether to train hard or back off.
Vitality age explained
What vitality age means, how it reads everyday wearable data, and why the gap from your real age is the number worth watching.
What is a good HRV by age?
Typical HRV ranges by age, why the textbook numbers don't match what your watch shows, and why your own trend matters more than any chart.
Biological age vs chronological age
What separates the two, what actually moves the biological number, and how wearable data approximates it between checkups.
