Tips for more accurate data recording

  • Wear the watch tightly on your wrist, bringing it toward the elbow and avoiding the wrist bone. 
  • Wear your watch for at least 4 hours during sleep at night. 
  • For accurate results, we recommend wearing the watch at least 5 nights a week. 
  • Charge the watch’s battery to at least 30% or more before going to bed in order to measure your skin temperature. 
  • For accurate measurement, please ensure that the surface of the infrared temperature sensor lens is clean. 
  • Accurate skin temperature measurements may be difficult if there are dust particles or stains on the surface of the infrared temperature sensor lens. Please wipe with a soft cloth or cotton swab. 

Other Precautions for use

  • The intended target group is women of reproductive age who are 18 years old or above.
  • We recommend wearing the watch for at least 4 hours while sleeping at night (between 7pm and 9am), at least 5 times a week. The predicted values can be affected by the way the watch is worn, the input value, and surrounding environment, etc. 
  • When travelling abroad or changing the time zone, the time zone of the phone is recommended to be set so that the exact sleep time can be recorded. 

Please note: 

  • Do not use data from Cycle Tracking to diagnose health conditions, including using the skin temperature data to diagnose fever. 
  • The user is not intended to interpret or take clinical action based on the app output without consultation of a qualified healthcare professional.
