If you're wondering how we use a sensor patch and an app to detect your ovulation, then you've come to the right place.

Our true hero, the smart patch with integrated sensor.

Unseren High-Tech Patch trägst du an maximal 7 Tagen deines Zyklus seitlich dezent an der Brust und diskret unter deinem Arm, wo er kontinuierlich deine Körpertemperatur in festgelegten Zeitintervallen misst und aufzeichnet.

Wie bekomme ich die Daten auf mein Smartphone?

Das funktioniert mit der bekannten NFC- Technologie. NFC steht für „Near Field Communication“ und ist eine schnelle und strahlungsarme Technologie zur kontaktlosen Datenübertragung.  

You know it from contactless payment and electronic passports.

Our patches are only intended for a single application cycle.

The femSense Patch sensor uses a battery as a power source and must not be disposed of with household waste, but in accordance with the respective national regulations for small electrical appliances.
