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.

When Daysy did an app update they… When Daysy did an app update they didn’t notify any of their customers that they would no longer be able to edit their mensuration period. This meant for me that my cycle was thrown off which took months to get back on track. I have seen a lot of articles that state their research is not accurate and I have lost my trust in them.

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!
