Apply patch
The app shows you when to apply your first patch and guides you step by step through the application.
Ovulation recognised!

When you ovulate, your body temperature rises and your measured ovulation is displayed in the app.
Once your ovulation has been confirmed, you can remove your patch.
Voices from our community
You need to bear this in mind when wearing your patch
You can do this with the patch

The patch is a disposable product
Do not wear it for longer than 7 days. If it is reused, the adhesive strength of the patch is no longer guaranteed and skin irritation may occur.
Do not use the patch if you are ill
Elevated temperature and fever can affect your body temperature and therefore the measurement.
In case of itching...
If you experience itching or other discomfort after applying the patch, please remove it.
You have a pacemaker
If you wear a pacemaker, only attach your patch to the side of your body away from your heart, otherwise the smartphone could interact with your pacemaker
Variety is key
Change the side on which you wear the patch with each cycle (unless you have a pacemaker).
Recycling
Please do not dispose of the patch in normal household waste. You can find more information on this under Recycling in the menu "Product"
