How OvulaRing works

The OvulaRing method uses the widely known symptothermal method (single-point basal body temperature measurement as part of NFP) and takes it to the next level!

Continuity instead of a single daily reading

OvulaRing measures continuously instead of just once, detecting even the smallest shifts in temperature level. This means OvulaRing can identify ovulation more precisely than conventional cycle computers.

Precision and safety

Thanks to the detailed temperature curve, our medical algorithms identify, among other things, your fertile phase and the timing of ovulation with the highest possible precision.

Your individual fertility

Our algorithms provide insights into cycle and fertility patterns, which form the basis for predicting your next ovulation. They can also detect signs of hormonal cycle disorders (PCOS, luteal phase defect or Hashimoto’s).

Real cycle experts

Behind the medical algorithms is a team of experienced cycle experts. Our specialists create individual cycle analyses and advise our customers on topics such as trying to conceive, cycle health and possible therapeutic measures.

Safe, precise, uncomplicated:
why OvulaRing is the best cycle tracker

It’s for Everyone – suitable for all cycle lengths

Is your cycle extremely short, very long or highly irregular? OvulaRing works for all cycle types—for example, for women with PCOS. This has been confirmed in three medical studies across a wide range of cycle types.

Practical – you won’t feel it

You wear OvulaRing like a tampon and remove it only to transfer data and during your period. With OvulaRing you can do everything as usual: sport, sauna, sex—there are no restrictions. Your individual lifestyle does not affect the accuracy of the results.

Get to your baby dream faster

OvulaRing users know their cycle in detail and get pregnant on average in just 4.2 months. With OvulaRing, you not only get certainty about your fertile days, but also about your individual cycle health. This makes it easier to detect hormonal cycle disorders. OvulaRing shows you daily when your chance of conception is highest—so you won’t miss your most fertile days anymore.

A new body awareness

Our happy users confirm it: by observing your cycle precisely with OvulaRing, you develop a completely new awareness of your body. OvulaRing can help you read your body and its needs better and live in harmony with your cycle.

Hormone-free and without side effects

OvulaRing works without hormones and is also free of plasticizers. The excellent biocompatibility of the material has been confirmed in several medical studies.

No Gaps! – seamless tracking of your cycle

OvulaRing records your core body temperature with 288 measurements per day—every 5 minutes, 24 hours a day. That’s why OvulaRing provides information about your cycle health with a level of precision no other tracker can match.

Timing is everything – your ovulation in real time

OvulaRing can tell you reliably whether you ovulate. It also tells you whether your cycles are healthy. OvulaRing learns your unique cycle patterns. Every day you can see your current fertility status as well as the prediction for your ovulation in the next cycle.

Certified, patented, safe: developed by doctors

OvulaRing is certified and approved as a medical device and is therefore subject to strict medical regulations. OvulaRing was developed by renowned gynecologists at the University Women’s Hospital in Leipzig. The method is based on 40 years of experience and scientific research. OvulaRing’s accuracy has been demonstrated in several medical studies.

Support for natural contraception

OvulaRing is a medical method for precisely determining ovulation and your fertile days. This way you get optimal support for natural contraception using the symptothermal method. OvulaRing supports natural family planning (NFP) and is used as a supportive NFP app to determine your fertile days. Instead of time-consuming measuring that’s prone to error, OvulaRing measures for you—precisely and reliably.

Cycle 1

Observation and analysis

In the first cycle, OvulaRing learns your individual fertility patterns. Even in your first cycle, you can already track your temperature very precisely. The analysis shows you whether you ovulated, when your fertile days were and how long your second half of the cycle was.

Startscreen App
Cycle 2

Daily updated
chance of conception

From cycle 2 onwards, your daily fertility status can be determined. After transferring new data, OvulaRing immediately shows your current chance of conception. The app works like an ovulation calendar, showing your chance of conception day by day and also when this fertile phase is over in your cycle.

With OvulaRing, you get a digital fertility calendar that helps you plan your fertile days in advance.

Pregnancy test and
due date calculator

The OvulaRing app includes an integrated pregnancy test. If a pregnancy is detected, you can also calculate your expected due date precisely.

Does OvulaRing work for me too?

Even very long cycles are often healthy and include ovulation. However, it can be harder to determine the exact day of ovulation. OvulaRing has been tested in independent medical studies for all cycle types. This means OvulaRing can provide precise insights into your cycle health even with long cycles.

Thanks to continuous measurement with 288 measurement points per day, OvulaRing can also show you whether you ovulate—and if so, when it happens.

Studies have shown that more than a third of women with PCOS ovulate and can get pregnant naturally. OvulaRing has also been clinically tested for women with PCOS and can reliably tell you whether you ovulate regularly and whether you can get pregnant naturally.

OvulaRing detects ovulation with a certainty of over 99% and can provide precise insights into your individual cycle health.

Have you been trying to get pregnant for a while and don’t know why it’s not working? Ovulation tests and basal body temperature tracking haven’t helped so far? Methods based on a single measurement per day can’t tell you what’s really going on in your cycle.

With 288 measurement points per day, OvulaRing can provide very precise insights into your individual cycle health. This way you can find out whether you ovulate or whether there are signs of a hormonal cycle disorder.
