Careful If you are thinking in investing in this device you need to remember one important thing: Daysy is, in the end, just a fertility tracking method. It DOESN'T protect you from unwanted pregnancy (even though the company tries to sell it as if it would, in a very subtle way, and of course without taking any accountability). I got unwanted pregnant with it 2 times, now we switched on using condoms only religiously. I know from 2 other women in my friends circle who had the same "accident". So, please be careful. I still keep the device tho, in the case i will want a baby in the future, because it gives you a better overview of the best fertile days. Oh, one more thing: Beware of the paid reviews (that are in high amount on Trustpilot as well) ;)

I love Daysy! The Daysy is amazing! I love it. I used the previous generation product, called LadyComp, preventing pregnancy for about 5 years. Once we decided to try, I got pregnant the very first cycle since I knew exactly when I ovulated. The Daysy is even easier than that and I'm so grateful for a natural alternative to hormonal birth control.

Daysy sync is trash This app is horrible. Yes the tracking feature is cool when I can get my Daysy to SYNC! Which is impossible 95% of the time. Yes the blue tooth is on, yes I have reread the instructions 80 times, yes the notifications is on, yes I let the Daysy fall asleep then try to resume syncing. It takes me having to log out of the app entirely and sometimes uninstall then reinstall just to get a reading. And that sync button in the upper right hand corner is completely useless. It does nothing. No one wants to do that in the morning every day because it won’t automatically sync or even manually sync for that matter.

Choose Daysy Wow, where to begin. This device has changed my life. To have the option to not take a pill everyday and still have a safe, natural, effective way to avoid an unwanted pregnancy is remarkable. Apart from this, the staff behind Daysy offers exceptional customer service. They go above and beyond to meet your expectations. There is not enough great things for me to say about this company. Choose Daysy.

Love it, but could be better.. Love it, but it could be better. I noticed I’m missing readings because I’m half asleep and I think it’s taking my temp but come to find out that I accidentally clicked the button twice and it was trying to sync instead of take temp.. Should probably change the blue tooth connection color and temp reading color. When you’re half asleep they look the exact same. Also, when using the app you can’t make a note or update sexual activity if it was a week ago. What’s up with that?
