A free companion to your Apple Watch
Body Clock + Apple Watch
Your Apple Watch tracks how your body is doing. Body Clock is a free chronotype guide that tells you what to do with it: the best times to eat, move, focus and sleep. You read your body, we help you time your day.
Better together
One measures your body. One tells you when to act.
The Apple Watch is one of the best trackers made. It shows you the data. Body Clock is the circadian-science side: free guidance on the timing a tracker never gives you.
Your Apple Watch

- Heart rate and ECG

Body Clock

How they fit
Two halves of the same picture
Your Apple Watch shows you the data. How you slept, how you recovered, how ready you are today.
Body Clock gives you the playbook. From your chronotype, the hours your body is built to eat, move, focus and rest.
You put them together. Read your body with the device, time your day with the guidance. No app to connect, nothing to sync.
New to Apple Watch?
If you want a tracker to pair with the timing, the Apple Watch covers the essentials and a great deal more.
Explore Apple Watch→The bottom line
Apple Watch is the tracker. Body Clock is the free guide that helps you make the most of it.
We do not track anything, and we are not a gadget. Body Clock is a website: the "what to do and when" a tracker leaves out, built from circadian science and your chronotype.
Have one already? Your free chronotype guide takes two minutes.
Common questions
Do I need to connect or sync my Apple Watch to Body Clock?+
No. Body Clock is a website, not an app that plugs into your Apple Watch. There is nothing to pair and nothing to sync. You read your body with your Apple Watch, and you use Body Clock's chronotype guidance to time your day.
Is Body Clock free?+
The 2-minute chronotype quiz and your core timing guidance are free. A deeper, fully personalized daily protocol is a paid add-on, but you get real, usable guidance without paying anything.
Does Body Clock replace my Apple Watch?+
Not at all. They do different jobs. Your Apple Watch measures what your body is doing. Body Clock tells you the best times to eat, move, focus and sleep for your chronotype. Most people use both.
