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".
Important:
- 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 fertility Reviews
Didn’t work
The app is horrible, it gives little to no information
The patch was even worse, I had it on for a week and it never detected ovulation. I had an LH rise and then ovulation was confirmed several days after through bbt but somehow the patch never picked it up. When I asked support they said I should have left it on because it probably would have detected it the next day, convenient, however that would have been over 48 hours after I actually ovulated and the egg would be long gone. I’m not really sure how anyone has had success with this, maybe I got a bad patch? But for $40 each I will NOT be trying it again. It also left a horrible rash and a blister. 0/10 recommend
Patch application date not flexible
I was extremely optimistic to start and brushed off the bad reviews because I am am willing to try anything at this point in TTC. I track my LH with OPK strips and input the data in the app. The app claimed my window was March 11-14. My LH surge occurred March 11. So it never detected my ovulation because it had me apply the patch too late. I had ovulation confirmed by ultrasound March 11. So had I followed the app advice, I would not have been testing in my window, which is really sad to think might be happening to other users. To put it into perspective I ovulated on CD-14, which is really normal. I hate that the app didn’t adjust the application date and I couldn’t apply sooner and start reading it despite my OPK data. The app is not good, it doesn’t show any data and doesn’t adjust to inputted data. The patch gave me a dermatitis rash that I’m having treated now, and it was extremely uncomfortable. Until this is fixed, I cannot recommend it to anyone and will let all my patients know that it is stress inducing, uncomfortable and inaccurate.

Enjoying the new update. I have been using femSense to track my cycle. The app makes it easy and the patch is barely noticeable for me most of the time.
Horrible
This product is horrible. It has you put in your previous cycles and my first patch it had me apply it on my peak day and the patch didn’t even sense it. (I use other devices so I know I was at peak and ovulated the next day) not sure why it wouldn’t have me apply it sooner when I put the results of my opk in the app. Makes no sense. Waste of $40!! I’m so angry! Do not buy!
Ok, not great
I thought that you would get a readout of your temperature measured by the patch but it doesn’t. I wish I could actually see in a graph what the patch measured. There is also no way to add your BBT measured throughout your cycle, you can add a bunch of other symptoms to improve your predictions like OPK and physical symptoms but nothing for BBT. I have used it for one cycle and will try again next cycle. The patch did say it detected my ovulation but I forgot to scan my patch until I was drinking coffee so I am not 100% sure it it just registered my higher temp from my warm drink or I did in fact have a higher BBT. Once the patch detects ovulation you can no longer scan it to confirm the higher temp.
poor design-
no data analysis for the user who has paid quite a lot for this patch -
no proper instructions- for me it didn’t even tell me whether ovulation occurred or not - just prompts me to do a pregnancy test in 11 days which is so ridiculous- doesn’t even prompt when you can remove the patch!
I regret getting 3 patches - total waste of money and time -will stick with inito
Honest opinion
I was so unsure about getting this app let alone the patch. Thankful that I did. I see a lot of negative but I think it’s different for everyone. I will say this the price in the patch is a little up there for sure especially since it’s only one patch, but for me it worked. I definitely think there could be a little more to this app for sure, like it be nice if we could see the temperatures and more data that it’s taking when we sync our phone to it to see if we ovulation. For me it wasn’t bad wearing it but it is a stick on so after a couple days it was a little uncomfortable but nothing crazy didn’t really notice it and I’d almost forget about it. Now I have pcos and used this unsure I was ovulating and just before my last day it told me I was and I couldn’t of been more happier to have that confirmed ovulation. It would be nice if it should like times an all that along with the other things I mentioned before. So if your getting it just know it doesn’t show you really anything you have to fill out the information like any other app witch to me not a problem. An wear it the full time it will tell you to take it off once you have confirmation of ovulation. I know there’s a bunch of bad reviews for me it wasn’t bad tho everyone will be different though. I think it was worth a try.
Terrible Product
App instructed to apply patch days after my LH patrols peaked and a PdG test confirmed ovulation. Does not give you any info accept "didn't detect ovulation". Well duh! It had me apply the patch after I had already ovulated. Then told me to removed on 7th day. WASTE OF MONEY
The App doesn’t update
The App doesn’t update when you put data in. You enter data and save it and it does nothing it goes back to whatever it wants to enter. Maybe the app is faulty. Hope this patch works for me despite the app having issues because we have been trying for a child for a long time.
This doesn’t tell you anything?
The app doesn’t tell you anything. It doesn’t give you any data, you can’t see your temp readings… nothing. It’s just “scan your patch” and then “femsense didn’t detect ovulation”… okay? But what days are you tracking? Why can’t I see if? How do I even know this thing is doing something? Seems like an awful lot of money for something that I don’t have any concrete proof of it working.
