Awards: Awarded three years in a row (2022 | 2023 | 2024)

3-time winner of the German Health Award for "Best Cycle Tracker"

The German Institute for Service Quality and ntv have once again honored the most popular companies with the “German Healthcare Award.” The award is based on the results of a large-scale survey in which approximately 45,000 people participated.

The survey examined customer satisfaction in the areas of value for money, product range, and customer service. Factors taken into account included, for example, the quality and usefulness of the products, the variety of products offered, reliability, and the availability of contact options in person, by phone, chat, email, and social media channels, as well as responses to customer inquiries in terms of expertise and friendliness.

The German Health Award has been presented in the years 2022, 2023 and 2024 awarded in the “Cycle Tracker” category. Unfortunately, this category didn’t exist in 2025, so we don’t know how we would have fared 😉

Why OvulaRing Stands Out as the "Best Cycle Tracker"

Continuous core temperature (24/7): The vaginal biosensor takes a reading every 5 minutes (≈288 readings per day)—regardless of wake-up times, sleep, or daily fluctuations.
Medically certified: CE-marked medical device (Class IIa).
Detailed cycle insights: Personal patterns instead of averages – helpful for irregular cycles and Desire to have children.
Simple for everyday life: As comfortable to wear as a tampon; data is automatically tracked.
Excellent & Recommended: Winner of multiple awards (including the German Health Award) and highly rated by users.

Which approach is right for you?

Heavy periods / irregular cycles / desire to have children

OvulaRing – Continuous basal body temperature tracking 24/7; ideal if you want to reliably track your individual cycle and patterns.

Symptothermal method with “single-point measurement”

trackle (measure at night) or myNFP/Lady Cycle (App-only) – symptothermal method with temperature and Cervical mucus.

Simple BBT Computer

Daysy – Basal body temperature in the morning; no cervical mucus. Consider the available evidence and your specific purpose.

Tip: For effective contraception, you need to use the correct method (e.g., STM) and/or follow the intended use, depending on the product. No period tracker protects against STIs.

Comparison of measurement principles: continuous core temperature vs. BBT/STM

aspect	OvulaRing (continuous, 24/7)	BBT/STM (morning/night)
Measurement time & -frequency	every 5 minutes, 24/7 (core temperature)	once a day (basal) or only at night
Everyday influences	robust data density, less susceptible	quite susceptible to disruption (sleep, time of day, stress)
Data depth	Individual patterns, phase progression	point values, manual classification
Cervical mucus (STM)	Required for STM via the OvulaRing app	Required for STM (App/Manual)
Area of application	all cycle types, including irregular	for regular cycles; requires some learning & Routine

Note: trackle (STM) is worn at night; Daysy is a basal body temperature (BBT) monitor used in the morning; app-only methods (myNFP/Lady Cycle) require consistent tracking & Mucus observation required.
STM … Ssymptothermal method
BBT … Basal Body Temperature Method

FAQ - Best Cycle Tracker: OvulaRing

Is OvulaRing a medical cycle tracker?

Yes. OvulaRing is classified as a medical device (CE, Class IIa) in the EU.

What is the difference between this method and others (BBT/STM)?

BBT/STM is based on a single daily or nightly measurement and additional cervical mucus observation. OvulaRing continuously measures core body temperature (24/7) and automatically analyzes the data.

Is the OvulaRing suitable for women with irregular cycles?

Yes. The high data density makes individual patterns visible—even in the case of longer or irregular cycles.

Will OvulaRing help me get pregnant?

The comprehensive database provides precise insights into ovulation windows and cycle phases—a valuable resource for those trying to conceive.

Is OvulaRing effective as a form of birth control?

OvulaRing is an excellent way to support natural birth control—but to be sure you don’t get pregnant, you’ll need to use a contraceptive method of your choice (such as a condom).

Ready to really understand your cycle?

Get started with OvulaRing and use in-depth medical data to support your journey to parenthood, track your cycle, and discuss your health with your doctor.

OvulaRing Reviews

Mom of two despite PCOS, thanks to OvulaRing

For eight years, Nicole tried to get pregnant. At the fertility clinic, she was diagnosed with PCOS, and it was determined that her husband had poor sperm quality.

Before she discovered OvulaRing, she had gone through several cycles of hormone treatment—without success. With OvulaRing, she then realized that she was ovulating despite having PCOS. Knowing when she was ovulating, she has already gotten pregnant twice, completely naturally. Today, she is the happy mother of two wonderful daughters.

OvulaRing is suitable for all types of menstrual cycles

In recent years, OvulaRing has helped many couples fulfill their dream of having a child and use natural contraception. We are grateful for the many OvulaRing reviews that have been shared with us.
