About this app

There for you in every situation - femSense helps you to understand your cycle and your fertility.

- Planning a pregnancy: femSense reliably shows you when you are ovulating and when your fertile days are. That way, you can easily plan a pregnancy.

- Free period calendar: You can also use femSense as a cycle tracker to get to know your own body better. The app always tells you which cycle phase you are in and when your next period is due.

Better together: our app and our smart patch. How femSense works

- The temperature method is cumbersome & old-fashioned? We don't think so. We've brought it into the 21st century and developed a smart sensor patch that measures your basal body temperature 24/7. The attendant app tells you when you're ovulating and when your fertile days are.

- No patch, no problem. You can also use the femSense app as a free cycle tracking app without a patch, and without any annoying ads! In addition to your period, you can also track your symptoms and view recurring patterns in the stats. This way you will get to know your body even better and live in harmony with your cycle.

It's that easy:

Download the app, register, and select mode:
- Want to understand your fertility and cycle better? Then choose "Fertility Awareness".
- You want to have a baby? Then choose "Get pregnant".

You can buy our patches directly in the app or in our online store.

With the combination of the femSense app and the smart patch you can:

- In cycle tracker mode, see your fertile phase and learn your daily fertility status (high fertility / low fertility).

- In fertility mode, find out your 4 most fertile days and get pregnant in a targeted way.

- Find out when (and if) you ovulated.

What makes femSense so unique:

- Our Hero, the smart patch, has an integrated temperature-sensitive sensor that continuously and all by itself records your body temperature readings at set time intervals, reliably detecting your ovulation.

- Short wearing time: You wear the patch on a maximum of 7 days a month - the app tells you when.

- Comfortable to wear: our patch is ultra-thin, discreet, skin-friendly (it's gentler on your skin than a conventional sensitive patch!) and medically tested.

- NFC technology: you read your patch using low-radiation NFC technology. NFC stands for "Near Field Communication." You already know it from contactless payment and electronic passports. Your data is protected because the short reading distance makes it impossible to access it without permission.

- Speaking of data. Privacy is a big concern for us We handle your data carefully and would NEVER sell it to third parties. Learn more about this on the femSense website under "Privacy Policy".


- femSense does not replace a consultation with a doctor. The information in the app is recommendations and cannot be used for medical purposes. Always seek medical advice before making medical decisions.

- femSense is not (yet) an officially recognized means of contraception.

- femSense is a registered trademark of SteadySense GmbH.

I can't get my phone to connect with the patch!! I tried reaching out to the helpline but they never got back to me! After spending so much money, I was hoping for a better experience.

Highly rate this app. Download the app in February, used it a lot and then found out I was pregnant in June. This app is really good at keeping records of everything but remember to be as detailed as possible. I truly believe that helped for me eg light period, middle, when it ends, your mood etc. It helps map out your exact ovulation days. I believe it is how I got pregnant so quick.

I'd like more in app development for TTC women For 5☆. It would be nice to see my temp when taken or even just a history of temp and when taken to keep track. Ect more ability to add more info for a truly accurate detection. I just finished my first month. it said it detected ovulation so let's see if it tracks as well as it says. The patch it's self stayed on beautifully & I didn't feel it at all.
