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.

What can affect my temperature?
If your temperature is affected, you can exclude individual temperature readings. To do this, simply select "Exclude temperature." Additionally, under "Disturbing factors," you can document which factor may have influenced your temperature. For example, if you consumed an excessive amount of alcohol on Saturday evening and measure your basal temperature on Sunday morning, you should exclude Sunday's temperature as it has been influenced. The excluded readings will then be appropriately considered by the algorithm. You should also measure on sick days and simply exclude the value afterwards.
Do I have to measure at the same time every day?
The most important thing is to measure your temperature immediately after waking up, before any activity, while you're still in bed. The tolerance window is four hours in the morning, during which your temperature should be measured each day.
What happens if I forget to measure?
For the calculation of your fertile phase, the six days before and three days after ovulation are relevant. Since ovulation can shift, you should take at least six measurements per week. If a measurement is missed, you should log your body signals for that day and wait for the next measurement.
Does the app work on my smartphone?
The Ovy app requires Bluetooth Low Energy technology 4.0 for the Ovy Bluetooth Basal Thermometer.
The Ovy app is supported from iOS 10.0 and Android 5.0 (Lollipop).
On some Android devices, temperature transmission (in the background) works with limitations. You can find a list of these Android devices in our terms and conditions.
