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.

Not amazing I've had this for 3 months now and to be honest I still don't really see the fuss and regret paying $500 (aud) for it. Even when I take my recordings everyday, it still gives me the same information that my free flow app gives as far as when I'm fertile and when I'm not and flow was way more accurate about my period. Since the new update daysy has just become even more frustrating as the app doesn't record all data that has been taken and won't let you edit your period-whose period only goes for three days? I haven't got pregnant so i guess that counts for something but I would seriously caution anyone wanting to buy this, I think it is a bit of a rip off

I Love my Daysy I began using Daysy a little over 2 years ago. It has brought a lot of insight on how my hormones and temp regulate with eachother. I love how I don’t have to suppress my ovulation (birth control) and i can naturally monitor my cycle to prevent pregnancy. Whenever I’ve had issues or questions regarding my Daysy, the turn around time has been so quick!

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 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!!
