Very satisfied
The app is incredibly intuitive and easy to use. I'm particularly impressed by the well-thought-out design – modern, clear, and appealing. But what really convinces me is the personal and reliable support. Instead of a chatbot, you quickly get a friendly answer from real people. I've been using the app for many years.

Can I also use the Ovy app to get pregnant?
Yes. When you start using the Ovy app, you'll be asked what your goal is. Here you can choose between contraception and getting pregnant. You can change this selection later in the settings.
In "Trying to Conceive" mode, the Ovy app predicts your six most fertile days and the day of ovulation. It also calculates the start of your next period and indicates when you can take a pregnancy test.
If you become pregnant using the Ovy app, you can switch to pregnancy mode to track your pregnancy.
Is the Ovy Bluetooth thermometer compatible with Android smartphones?
On some Android devices, background temperature data transmission is limited. A list of affected Android devices can be found in our Terms and Conditions .
Do I need prior knowledge to use the Ovy app correctly?
The app offers you various background information on the method. In addition, a tutorial on how to use it is shown before you start.
To use the symptothermal method, you need a basal thermometer to measure your waking temperature (e.g., the Ovy thermometer) and a medium for documentation (e.g., the Ovy app).
