"Ich nutze das femometer zur Verhütung und ärgere mich mittlerweile, dass ich es nicht schon eher bei Kinderwunsch kannte! Es funktioniert kinderleicht. Die App sagt mir genau, wann der Eisprung vermutlich eintritt und sagt mir auch im Nachhinein anhand der Temperaturkurve, wann er war. Dementsprechend wird verhütet oder bei Kinderwunsch dann eben nicht. Die app hat mir bisher auch auf den Tag genau vorausgesagt, wann meine Periode einsetzt. Seit 7 Monaten hormonfrei und nicht ungewollt schwanger! Also ich kann es nur weiterempfehlen!!!"

“I used the Femometer for contraception and now I’m annoyed that I didn’t know about it earlier when I wanted to have children! It works very easily. The app tells me exactly when ovulation is likely to occur. It can also tell me afterwards, when ovulation did occur, by simply analyzing my body’s temperature curve. You can use this information and decide to use contraception during your fertile days or plan your pregnancy. The app has so far predicted exactly (to the day!) when my period will start. For 7 months I’ve been hormone-free and have been consciously choosing to not be pregnant. I can only recommend this product!!!”

"Temperaturanalyse meinen durcheinander verstehen und wieder normalisieren. Das tolle dabei ist, man misst vor dem Aufstehen, wobei das Femometer einen Speicher hat und ich mir im Halbschlaf keine Temperaturen merken muss. Kurve wird durch die App erstellt, die natürlich kostenfrei und einfach zu bedienen ist. Zusätzlich habe ich auch Ovulationstest genutzt: Durch ein Foto des Tests konnte die App mir sagen wie hoch der Wert ist und ob ein Eisprung ansteht oder nicht. Für mich das Beste was es gibt, weil es hat mir dabei geholfen meinen größten Wunsch zu erfüllen!"

“Temperature analysis has never been easier. The great thing about the Femometer is its simplicity. I’m able to take measurements first thing in the morning, (while I’m still half-asleep), and the temperature is saved by the Femometer. I can send the measurement to the app for tracking and the app is free and very easy to use! I also use Yoyoni’s ovulation tests. I keep track of my ovulation window with the app and know exactly when I am ovulating. These products are the best solution for me, and it’s allowed me to understand my body and fulfill my greatest wish – becoming a mother.”

“Erst war ich etwas kritisch, denn ich habe diese Verhütungsmethode schon einmal mit einem analogen Thermometer versucht. Nach kurzer Zeit habe ich es aufgegeben, weil mir das manuelle Eintragen meiner Temperatur morgens nach dem Aufwachen zu lästig war. Mit dem Femometer von Yoyoni ist das nun ganz einfach, da es meine Messdaten direkt per Bluetooth an mein Smartphone sendet und ich meinen Zyklus sofort im Blick habe. So habe ich meinen Körper erst richtig kennen- und lieben gelernt!”

“At first, I was a little critical because I have tried this method of contraception with an analog thermometer. After a short time, I gave up because I was too annoyed at having to manually jot down my temperature in the morning after waking up. Temperature tracking is now very easy with the Yoyoni Femometer, as it sends my measurement data directly to my smartphone via Bluetooth. I can understand and see my cycle immediately. The Femometer really helped me to get to know and love my body!”

“Echt eine tolle Sache! Vor dem Femometer hatte ich ein normales Basalthermometer, habe aber ständig vergessen, meine Temperatur in die Liste einzutragen. Das Femometer von Yoyoni sendet meine Messdaten automatisch per Bluetooth an die App auf meinem Handy. Die App ist übersichtlich und einfach zu bedienen. Ich kann sogar die Lautstärke des Pieptons einstellen. Ich messe nun jeden Morgen meine Temperatur und lasse die Daten aufs Handy senden. Außerdem kann ich LH-Werte und Ultraschallfotos in der App speichern. Mit dem Femometer bin ich schon im ersten Zyklus (gewollt) schwanger geworden. Egal ob Kinderwunsch oder Verhütung, ich kann das Femometer von Yoyoni auf jeden Fall nur empfehlen! Nach der Schwangerschaft werde ich es sicher wieder verwenden, dann erst einmal zur Verhütung…”

“A great invention! Before the Femometer, I had a normal basal thermometer, but I kept forgetting to write my temperatures down. The Yoyoni Femometer automatically sends my measurement data to the app on my mobile phone via Bluetooth! The app is clear and easy to use. I can even adjust the volume of the beep. I now take my temperature every morning and have the data sent to my cell phone. I can also save LH levels and ultrasound photos in the app. With the Femometer, I (intentionally) got pregnant during my first cycle. Regardless of whether you want to have children or use contraception, I can definitely recommend the Yoyoni Femometer. After my pregnancy, I will certainly use it again for natural contraception.”

“Da ich eine Hormonstörung habe und meine Regelblutung sehr unregelmässig ist, war es für mich sehr schwierig, den richtigen Zeitpunkt für eine Schwangerschaft zu finden. Mit dem praktischen Femometer von Yoyoni bin ich schon im 2. Monat schwanger geworden! Es ist so einfach: Aufwachen, Temperatur messen, Daten ans Smartphone senden. Alles ist übersichtlich gespeichert und ich habe volle Kontrolle.”

“Since I have a hormone disorder and my period is quite irregular, it was very difficult for me to find the right time to conceive. With the practical Femometer from Yoyoni, I got pregnant in the 2nd month! It’s so easy: you wake up, measure your temperature, and send the data to your smartphone. Everything is clearly stored and I have full control."

You can start testing a few days after your period has ended. In the Femometer app, your fertile phase is marked on the calendar. The measurements should be taken daily and ideally at about the same time. Make sure not use the morning urine and don’t test right before bed (urine that is too concentrated or too diluted can falsify the result). You should also collect midstream urine, as this is known as the “cleanest” urine.

Midstream urine is a urine sample that is not obtained at the beginning of micturition (urination). Instead, it is obtained from the urine stream that is already running. In order to get a correct result and to avoid contamination with bacteria, you should use midstream urine for a urine test.

The test is positive if the test line (T) is as dark as the control line (C). With your daily measurements, you will find that the test line gets darker and darker the closer you get to ovulation. By transferring your measurement results to the Femometer app, the app's algorithm recognizes when you ovulate and marks it in the app's calendar.

External influences such as alcohol and medication have different effects on the body temperature and urine of each person. Typically, one or two glasses of alcohol won’t make a significant difference in your measurements. After taking your measurement, you can see how these external factors affect the results. If you have a feeling you have drank too much, you can skip the LH measurement once to maintain the accuracy of your data.

We recommend making as many detailed entries as possible. This makes results and evaluations easier as more data can lead to higher precision. Tracking the measurement of your basal temperature in combination with observations of cervical mucus and ovulation testing gives our algorithm a strong basis for determining your results. In addition, you can see for yourself (in real time) how your body changes during your cycle and how to interpret the signs of fertility. We recommend the book Naturally and Safely by the NFP working group for detailed information on the symptothermal contraceptive method. You can buy it on our website.

Yes. Ovulation tests measure the LH level in urine. They give you additional security for hormone-free contraceptive as you won’t be solely relying on your basal body temperature during an irregular cycle. In the case of extremely irregular cycles, we recommend consulting a doctor to clarify what the causes may be. The BBT chart can provide your doctor with valuable information to help clarify the problem. Most imbalances in your natural cycle can be managed with herbal remedies.
