Lady-Comp fertility tracker

Natural family planning made easy!

Lady-Comp is an intelligent fertility tracker that helps you track your cycle naturally and plan your family.

The practical fertility tracker shows your ovulation up to 6 days in advance and supports you with many other features to fulfill your desire to conceive - whenever you are ready.


Ready, Set, Go - Reliable insights in just 60 seconds

This is how easy cycle tracking is with Lady-Comp:

After waking up, measure your basal temperature under your tongue.
Enter when you have your menstruation.
Lady-Comp displays if you are fertile or not.

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.

  • Red display = fertile/possibly fertile
  • Red display + cycle day flashing = Yay! Today is your predicted ovulation.
  • Green display = not fertile
  • Yellow display = learning phase/cycle fluctuation/possibly fertile
  • Light blue display = possible pregnancy
  • Blue display = probable pregnancy

All versions of Lady-Comp are 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.


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.
