Get to know your natural cycle with Lady-Comp!

Easy as 1, 2, 3 - How Lady-Comp works

Lady-Comp is easy to use. Simply measure your basal body temperature under your tongue for about 60 seconds every morning after waking up, and the fertility tracker will show you immediately which phase of the cycle you are in and whether you are currently fertile.

Lady-Comp is programmed to reliably calculate the time of ovulation and display it accordingly. How does this work? Quite simply: Ovulation causes the basal body temperature to rise slightly - a small step in the temperature curve, but a big step for you, because when you know your fertile window, you can plan your family without stress and speculation. 


Lady-Comp cycle computers are devices developed and manufactured in Germany since 1986. Lady-Comp is currently sold in 35 countries and successfully used by millions worldwide. Opt for endless freedom now with natural cycle control by Lady-Comp.

  • very high accuracy from day 1
  • easy measurement under your tongue
  • tried and tested & continuously developed for over 30 years

The digital alternative for family planning

Lady-Comp uses the Fertility Tracker Method (FTM) to determine very precisely which phase of the cycle you are currently in and whether you are currently fertile or not. With its intelligent algorithm, based on findings from 35 years of research and more than ten million evaluated cycles, Lady-Comp can determine non-fertile phases with accuracy - in less than a minute and without the time-consuming recording of cycle curves or diagrams. The highlight: Lady-Comp works 100% naturally and can even detect and tolerate irregular cycles and fluctuations.
