Worn overnight, the iFertracker collects a whole night of temperature data. And the advanced algorithm in the app provides the true basal body temperature, which is about 30 minutes before awaking. The app also records the daily reading and converts to BBT chart automatically. The user can easily understand the rise (ovulation day) from the chart and the notification of TTC in the app.
The data accuracy of the iFertracker makes it easier for doctors to evaluate basal body temperature and provide clinical advice. Clinical research shows that for women suffering from fertility problems while still having regular menstrual cycles, continuous measurement of whole-night body temperature predicts day of ovulation and ovulation cycle more accurately than ultrasonic monitoring of type-B follicle size.
