How smart-ring cycle insights work
Temperature trends, logged dates, prediction and fertility limits.

Definition
Cycle insights combine overnight temperature trends with dates and other signals to estimate future phases.
Bottom line
Use them as context, not contraception, pregnancy confirmation or diagnosis. Illness, medication and travel can shift predictions.
The ring sees a trend
A finger sensor observes local temperature variation from baseline; it does not directly observe ovulation.
Partner apps are separate
Regulatory status, eligibility and fees belong to the connected service and market.
