ScanWatch 2 includes a temperature measurement technology that helps provide more accurate insights into your menstrual cycle. By wearing your watch at night, the device can measure your nightly continuous body temperature and detect small variations that are typical across different phases of the cycle.

During the cycle, your basal body temperature (the resting temperature measured during sleep) tends to shift. For example, after ovulation, a slight rise in temperature is often observed. ScanWatch 2 captures these nightly temperature changes and uses them as input for our prediction algorithm.

The more often you wear your watch at night, the more reliable the temperature data becomes. This helps the algorithm refine predictions for upcoming cycle phases and retrospectively confirm fertile windows, giving you a clearer picture of your cycle over time.
 

Key points to remember:

• Wear your watch consistently during the night to capture accurate temperature data.
• Temperature variations are analyzed alongside other cycle information to enhance the precision of predictions.

• Your watch can retrospectively confirm fertility windows, helping you better understand your cycle patterns.

   

Important: The fertility window feature is intended for informational use only. It is not a medical feature and should not be relied upon for contraception or to achieve pregnancy. For personalized reproductive advice, consult a healthcare professional.
