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.

Literally the biggest waste of money on… Literally the biggest waste of money on the entire planet. Doesn't sync with your phone, takes forever to take your temperature and straight up doesn't work. I have reached out to customer support multiple times and they have told me to download beta versions of their app and all different types of solutions and nothing ever works. Absolutely garbage. Don't waste your money.

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 The app feels outdated and pales in comparison to competing apps like Flo.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 But €300 is ridiculous for how cheap it feels, how outdated it is, and how complicated it is.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.

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!

Not easy to use Not easy to use. Not as insightful as I would have liked into my overall cycle health. Hard to know if it was worth it. Setting it up and troubleshooting the issues was not easy and can't say that I had a great customer service experience--not great return policies. I still think my Daysey is broken but now I'm stuck with it and no one there seems to care. Overall not happy with this purchase and think that the company could do better to with customer service, instructions on use, trouble shooting and warranty.
