I can't imagine my life without the… I can't imagine my life without the Daysy! I'm super grateful for this device and trust its reliability. I value my cycle more since using the Daysy, and I love not being able to worry about condoms since I'm good to go on green days. My partner gets excited for my green days, and the waiting makes the experience even more special, without the worry!

I love my daysy but I'm facing a… I love my daysy but I'm facing a battery interruption issue for quite some time now, and nothing helps.. Customer service did not reply nor helped, despite having it for several months only. I'm so frustrated!!

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.

Works extremely well Daysy helps me monitor my fertility for preventing pregnancy, and it has worked perfectly so far. The app is great and I have had no issues with the device or the app. I love being able to download the charts and analyze my biology. Once I got a higher number of red and yellow days, so I reached out to customer support. Within one business day someone responded and provided an in depth analysis and advice.

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) ;)
