Since over 30 years the natural method to monitor your menstrual cycles with 99.3% accuracy.


By recording the Basal Body Temperature daily, Lady-Comp traces your unique menstrual cycle pattern.

After ovulation the release of natural progesterone prevents an other ovulation and raises your temperature slightly until the next menstruation. Lady-Comp detects this shift and indicates the infertile days with a green light with 99.3% accuracy.


A woman's cycle is as individual as her life and subject to many influences. Only 3% of women have a super regular cycle.

Lady-Comp knows that and works with a refined and tested algorithm to detect the current fertility status regardless of the day of ovulation and the menstrual cycle length. This allows women from the first to the last day of their fertile years to observe their menstrual cycles with Lady-Comp.

The charts and previsions are really useful
