3 x German Health Award “Best Cycle Tracker”

Factors such as product quality and usefulness, product range, reliability, local contact options, telephone, chat, email, and social media channels, as well as responses to customer inquiries in terms of advisory expertise and friendliness, were taken into account.

Why OvulaRing is the “best cycle tracker”

  • Continuous core temperature (24/7): Vaginal biosensor measures every 5 minutes (≈288 measurements/day) – regardless of wake-up times, sleep, or daily fluctuations.
  • Medically certified: CE-marked medical device (Class IIa).
  • Precise cycle insights: Personal patterns instead of average values – helpful for irregular cycles and trying to conceive.
  • Easy to use in everyday life: As comfortable to wear as a tampon; data is evaluated automatically.
  • Award-winning & recommended: Multiple award winner (including the German Health Award) and valued by users.

Which approach suits you best?

Maximum data density / irregular cycles / desire to have children

OvulaRing – continuous core temperature 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 evidence and your intended use.

Tip: For consistent contraception, depending on the product, you need the correct method (e.g., STM) and/or an appropriate intended use. No cycle tracker protects against STIs.

Comparison of measuring 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 interference (sleep, time of day, stress)
Data depth individual patterns, phase progression selective values, manual classification
Cervical mucus (STM) required for STM via OvulaRing app Required for STM (app/manual)
Area of application All cycle types, including irregular For regular cycles; requires learning and routine

Note: trackle (STM) is worn at night; Daysy is a BBT computer used in the morning; app-only (myNFP/Lady Cycle) requires disciplined measurement & mucus observation.
STM … Symptothermal method
BBT … Basal body temperature method

OvulaRing experiences

Mother of two despite PCOS thanks to OvulaRing

Nicole tried to get pregnant for eight years. At the fertility clinic, she was diagnosed with PCOS and her husband was found to have poor sperm quality.

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