What Cycle Tracking shows you
Simple logging, seen next to the rest of your data.
Log in seconds
Mark cycle days as they happen and see your history whenever you need it.
See it next to your trends
Your cycle sits alongside sleep, HRV, and resting heart rate, so patterns are easier to notice.
Always free
Cycle Tracking isn't a lifestyle or medical program slot - it's included for everyone, no limits.
How Cycle Tracking works
Two steps. Always available.
Log a cycle day
Add an entry whenever it happens - it takes a few seconds.
See your history
Review past cycles next to your other wearable trends, whenever you want.
Notice your own patterns
Compare your cycle history with sleep and HRV trends over time.
