Step three
Ovulation recognised!

Use your smartphone to read out your patch twice a day, preferably in the morning and evening, to achieve optimum results.

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.

Das musst du beachten, wenn du deinen Patch trägst
Das kannst du mit den Patch
Das solltest du nicht mit dem 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"
