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.

Absolutely love my Daysy Absolutely love my Daysy! I've contacted support twice now, once for a cycle question and, more recently, about a connection problem and both times the support was quick and efficient! Highly recommend getting a Daysy or Teena to help you understand your cycle better.

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!

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.

Definitely not worth your money This has to be my biggest Amazon purchase regret and I wish I could return it after 4 months of trying. It is so hard to use, hard to remember how to use, the app sucks, and this technology is not nearly as smart as it leads you to believe. You can’t track your period start days unless you remembered to take your temperature that morning and you can’t go back and update information from over 3 previous days so if you forgot to take it your temperature you’re screwed. You have to manually sync the Daysy to the app and the app to the Daysy- this is fairly straightforward but not something you’d expect from a €300 device. The app feels outdated and pales in comparison to competing apps like Flo. I sincerely do not know how this has 5 star reviews on every platform. If it were €20, it’s totally worth the money. Maybeeee €100. But €300 is ridiculous for how cheap it feels, how outdated it is, and how complicated it is. I seriously doubt this was even made by women for women.
