Fertility control
MY OVU is an inteligent ovulation thermometer with an application designed to more accurately determine your fertile days.
By monitoring your basal body temperature (BBT), you can determine your fertile and infertile days. Infertile days occur once or twice during the cycle: at the very beginning of the cycle (up to 5 days before ovulation) and approx. 48 hours after ovulation. They last until the next menstrual period.
IMPORTANT! If you have a short cycle, you should only assume one period of infertility – the phase after ovulation. The egg can only be fertilized within 48 hours of ovulation! Days after ovulation are called post-ovulatory infertile phase and last until the next menstrual period.


Precision control that gives you freedom
Trust the latest technology that guarantees the highest measurement precision.
Precision, convenience, discretion – the MY OVU ovulation thermometer is innovative in every way! It has made cycle tracking easier than ever before. We’ve placed a precisely designed computer system in a small, silicone vaginal ring. Safe, neutral, and comfortable for your body. Internal measurement of BBT using algorithms is much more accurate than traditional methods, which can underestimate fertile days by up to 24-48 hours.

How does it work?
Before going to bed, insert the disc into the vagina, like a tampon or menstrual cup. MY OVU will take the measurement and store the result in the device’s memory. In the morning, upon waking up, remove the disc and wash it. Transfer the data to the app, then put MY OVU back into the box.
Apply
Before falling asleep, place MY OVU in the vagina. The easiest way to do this is by bending the disc inward at the thickened area.
Fall asleep
MY OVU collects data while you sleep.
Synchronize
In the morning, remove the disk and wash it with soap. Turn on Bluetooth and send the data to your phone – just press the button on the disk’s bulge.
Read the measurement
In the app, you’ll find the current reading and forecasts for your cycle.
All the necessary information at your fingertips

The purple bar on the chart indicates the day of ovulation. The labels for days 1, 2, 3 indicate days of higher temperature, confirming ovulation.

In the calendar, you will find predictions for your future periods and ovulation, based on personalized data.

In the app, you can record your observations regarding, for example, the quality of cervical mucus and cervical position – they are also important for fertility analysis.
How are we better?
MY OVU is not just an ordinary ovulation thermometer or a regular period tracking app.
