Cycle Tracking not available? The region-model-age triangle

Cycle Tracking on Apple Watch has two tiers: basic cycle logging (available widely) and retrospective ovulation estimates using wrist temperature (requires Series 8 or Ultra, and is region-gated). If temperature-sensing features are missing, your region is the most likely culprit.

Why is Cycle Tracking with temperature data not showing?

Retrospective ovulation estimates require an Apple Watch Series 8 or later (or any Ultra model) with wrist-temperature sensing enabled. This feature is also region-limited. Basic cycle logging is available in many more regions and does not require a temperature-capable watch.

Two tiers of Cycle Tracking

Basic cycle logging and period prediction are available on Apple Watch Series 1 and later in most regions. The advanced features use wrist-temperature data and require Series 8, Series 9, or any Ultra model.

Temperature sensing needs about five nights of sleep data with Sleep Focus enabled before it establishes a baseline.

  • Basic logging: Series 1+, most regions
  • Temperature features: Series 8/Ultra, limited regions
  • Requires 5 nights of sleep data

Frequently asked questions

Where is Cycle Tracking with temperature available?

Apple's watchOS feature-availability page is the authoritative source. At the time of writing, the US, UK, Canada, most EU countries, Hong Kong, Japan, and Australia are included — but check the live page, as the list grows with each watchOS release.

Does WLOC enable Cycle Tracking temperature features?

WLOC can verify whether device location is the blocker, but region, model, age, and regulatory approval are independent requirements.
