Easy Tracking Without Mess and Fuss

Unlike traditional fertility trackers that require you to wake up early or pee on a stick every morning, Femometer ring makes ovulation tracking easier than ever. Simply wear the ring while you sleep, and in the next morning, you’ll see your real-time temperature data and ovulation predictions.

Ovulation Predictions with 99% Accuracy

Your basal body temperature (BBT) is the temperature when you're fully at rest. Testing BBT at sleep ensures a more accurate result, which improves the accuracy of ovulation prediction, providing you with precise fertility insights and improving your chances of conception.


“Femometer Ring has been a nice choice for my family planning journey. Tracking my BBT now becomes much easier than ever. The app offers clear insights into my ovulation trends and provides helpful guidance for TTC. It's helping me understand my body better and gain better control of my fertility. Highly recommended for anyone who needs a family planning!”

Clear Fertile Window Display

Easily identify your most fertile days with Femometer App. Healthy sperms can stay alive in a woman's body for 3-5 days. Timing is crucial; having sex before and during ovulation increases your chances of conceiving by 150%. With a clear prediction of your fertile window, you can make the most of each cycle.

Daily Insights for Conception Success

Navigate your fertility journey effortlessly with the Femometer. Discover your conception rate and receive tailored tips each day to optimize your chances. This fertility map ensures you never miss a fertile window. The more data you input, especially BBT info, the more accurate the predictions become.
