Love it, but it could be better. I noticed I’m missing readings because I’m half asleep and I think it’s taking my temp but come to find out that I accidentally clicked the button twice and it was trying to sync instead of take temp.. Should probably change the blue tooth connection color and temp reading color. When you’re half asleep they look the exact same. Also, when using the app you can’t make a note or update sexual activity if it was a week ago. What’s up with that?

At first nervous to try this method, but the reults have been great. Short history of myself, I was having some issues accepting different types of birth control, so I then decided to use the dasysy and I have noticed a huge improvement in my overall mental/emotional and physical health. Highly recommend for those with doubts.

The product works ! You need better customer service and better instructions manual. I had to YouTube for instructions online.

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.

I’ve been using Daysy for over 4 years now and I couldn’t be happier! After years of being on the pill I wasn’t comfortable with taking hormonal BC anymore and found this to be the best natural option. Daysy and the Daysy view app are both very easy to use, the customer service is great and I would say this is definitely worth the price! I’ve gotten more in tune with my body and my natural cycle, and I no longer have to deal with the stress of how synthetic hormones are affecting my body long term. I’ve since recommended it to friends who have also fallen in love and I will continue to use Daysy as long as I need her!

While the device seems to work well, it will not sync with the app.

I was really nervous about using daysy as my birth control method but it really came through and works for me and I’m able to trust my body without putting any chemicals into my body. Thank you daysy for changing my life.

Getting off hormones changed my life and i feel so safe using daysy!

I've been using Daysy since October and am really loving it so far! I think some improvements can be made to the app but the product works very well. I would definitely recommend.

I got pregnant while trying to prevent pregnancy.

I love the concept of this device, but unfortunately there have been many glitches with syncing to the app. I have been in contact with customer service in the past about this issue and I am disappointed that these issues keep happening, especially for the amount of money I spent specifically to have an app associated with my fertility device.

Lots of orange days despite being very regular and taking temperature daily AND using the device for 6 months.
FYI: orange days mean that the device advise caution. It does not know whether you are fertile or not. I had to purchase urine strips to pin point ovulation days with more precision.
All that said, I love my daisy. I just wish I had more green days. I should say that I am using Daisy for contraception not to conceive.

I love my Daysy! It is way better than using oral birth control because it helps you get in tune with your body and learn more about your cycle. I would recommend the Daysy to anyone whether it is for birth control or to help someone have a baby.

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’ve been using Daysy for 7 months after not liking the effects of the pill and not liking other options available to me for birth control. I’m still not pregnant so I’d consider it a raging success. That, and I’m not putting added hormones into my body every day.
