Why OvulaRing is more accurate than classic basal temperature tracking

Inside the body

Measures directly inside the body -
nowhere is temperature recorded more accurately.

Every 5 minutes

Captures even the smallest fluctuations. This means every cycle can be evaluated.

During the day

Measures during the day – essential to know whether today is a fertile day.

No daily read-out

You decide. Only read it out when you need it—whenever you want.

No charging

OvulaRing has a long-lasting battery that you don’t need to recharge.

Automatic analysis

You never have to interpret data yourself again. OvulaRing does it for you now.

How OvulaRing works

According to common opinion, a “normal” female cycle lasts 28 to 32 days and ovulation occurs in the middle of this cycle. But that doesn’t reflect reality—and it doesn’t take female individuality into account. With OvulaRing, the medical cycle tracker, you can measure your ovulation precisely. This is how OvulaRing works.

Studies also show that 70% of all women do not conform to this standard. Their individual cycle may be shorter or longer and still perfectly healthy. Ovulation also occurs—just on a different day. In fact, only a few women ovulate exactly in the middle of their cycle. No matter how your cycle ticks, OvulaRing determines your fertile days very precisely. In addition, you receive precise information about your individual cycle health.

OvulaRing receives German Health Award 2024

For the third time in a row, OvulaRing has received the coveted award in the “Cycle Tracker/Computer” category. We are grateful for the award and proud of what we have already achieved with OvulaRing.

What OvulaRing is suitable for

Trying to conceive

PCOS

OvulaRing was clinically tested in women with PCOS and was able to detect more ovulations than the fertility clinic using hormone tests and ultrasound.

Irregular cycles

Our ovulation detection is clinically tested for all cycle lengths. Healthy pregnancies have occurred with OvulaRing even with ovulation later than cycle day 80 and beyond.

Endometriosis

OvulaRing is not affected by endometriosis. All features are available to you.

After failed IVF

Many women have become pregnant naturally with OvulaRing after failed IVF treatments. Lisa shares her experience here.

Hormone intake

Time your progesterone intake precisely with OvulaRing and find out whether medications to stimulate ovulation are working.

Natural contraception

Irregular cycles

Our ovulation detection is clinically tested for irregular cycles too. Natural contraception is often possible even if your cycle is not regular.

After the pill

The hormonal shift after stopping the pill does not affect OvulaRing’s accuracy. You can see in the very first cycle whether ovulation has taken place. This means you can use OvulaRing to support natural contraception.

After pregnancy

After pregnancy, it can take a while for your cycle to settle again. With OvulaRing, you can track your first ovulation and switch straight to natural contraception.

Time to pregnancy

Would you like to avoid hormones so your body can prepare for pregnancy? Or would you like to bridge some time between an IUD and pregnancy? Then use OvulaRing to support natural contraception. Find out whether your luteal phase is long enough and whether you ovulate regularly.

Understand your cycle

PCOS

OvulaRing was clinically tested in women with PCOS. More ovulations were detected than were identified by hormone tests and ultrasound. Get clarity about your body now!

Perimenopause

Would you like to know whether you are still ovulating or perhaps have a shortened luteal phase? Or would you like to find out early when your body is shifting hormonally? Then use OvulaRing to keep an eye on your cycle health.

Training

Did you know OvulaRing was the first wearable to provide training recommendations based on your current cycle phase? With the Sport add-on, you get expert tips—for example on running, strength training and nutrition—specifically for women.

Start adapting your training to your individual rhythm now.

Cycle health

Would you like to know whether your cycle is healthy? Then use OvulaRing to check if and when you ovulate. Play it safe and find out whether your luteal phase is long enough.

After the pill

After stopping the pill, you can check whether you have a healthy cycle. By wearing OvulaRing, you’ll know whether you ovulate, whether your cycles are regular and whether your luteal phase is long enough.

Benefits of modern cycle tracking with OvulaRing

Suitable for all cycle types

Is your cycle super short, extremely long or even very irregular? OvulaRing records your personal cycle—no matter which cycle type you are. The OvulaRing method works for different kinds of cycles. This was confirmed in 3 medical studies across a wide range of cycle types.

Continuous measurement

With classic basal body temperature tracking, you don’t measure continuously—only once a day. To analyze your personal cycle much more precisely, OvulaRing measures around the clock and stores 288 data points per day. That provides far more information to pinpoint your fertile days. OvulaRing learns your very own cycle patterns and delivers precise results.

Practical and not noticeable

OvulaRing is as easy to use as a tampon—yet even less noticeable. While wearing OvulaRing internally, you can do everything as usual: work out, go to the sauna, have sex and enjoy your life. The automatic measurement inside the body delivers accurate results in any case—regardless of your daily routine.

Cycle analysis and results in real time

OvulaRing can reliably tell you whether you ovulate. You can also see whether your cycles are healthy. At first, the app learns your very own cycle patterns. Once your patterns have been identified, your fertility status is displayed day by day. This is how OvulaRing works.

Developed by gynecologists and clinically tested

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 is patented and approved as a medical device. Its accuracy as a modern method of cycle tracking has been demonstrated in several medical studies.

Free of hormones and side effects

OvulaRing works completely without hormones. The ring is also free from plasticizers and side effects—so it doesn’t put a strain on your body. OvulaRing is comfortable to wear and as easy to use as a tampon. The excellent biocompatibility of the material has been confirmed in several medical studies.

OvulaRing gets excellent reviews

Better understanding of my cycle

By recording my temperature, I was able to determine much more precisely when my ovulation took place and why I had to expect my period. It also helped me realize that I have a luteal phase defect.
