Lady-Comp - Natural family planning made easy!

The new Lady-Comp is all that you need for natural family planning combined in one device!

This makes it perfect not only for tracking your own cycle and distinguishing fertile from infertile days, but also for actively addressing family planning needs - naturally and with an independently tested accuracy (99.4%)*. Thanks to the intelligent algorithm, which is based on your own basal body temperature, 35 years of research, and the evaluated cycles,, the Lady-Comp knows exactly in which cycle phase you are and shows you at a glance whether you are currently fertile or not - from the first measurement on! In addition, the new interface, which has been completely revised and optimized, provides insights into your personal cycle history as well as a menstruation forecast for the next six months. The operation is totally intuitive, which at the same time allows a relaxed introduction to fertility tracking.

Lady-Comp is thus the first gadget to incorporate all the functions of Valley Electronics and their findings of the last 35 years. It is the star among fertility trackers, an expert in fertility tracking and the personal companion on your TTC journey. After all, the desire to have a child is a complex issue and Lady-Comp offers you the perspective to get pregnant without stress and guesswork.
