I am so confused on how to use it, how to charge it, how to sync it. i have called you guys and it confused me even more. I feel like I wasted my money

I love this product, I am able to track when I will be most likely to conceive and also prevent pregnancy. Condoms work will when used right and they are not always needed when you know you cannot get pregnant. I used the IUD for about a year and some and the back pain was not tolerable. I appreciate this invention to my core and value its company.

Love the new Daysy (so much easier!!) and the customer support team is always super helpful and responsive, and proactive about solving problems. It’s always delightful as well to find out how much is covered under warrantee as my device has needed fixing or replacement once or twice (in 3+ years of using it)

I love Daysy - the updated Bluetooth functionality makes it so much easier to use and this as a form of birth control has taught me so much more than any other form ever could. I am sooo happy I made the switch to his natural method 3 years ago!!

The days itself is pretty good... cool to know my fertility status, but it has a lot of troubleshooting. The app is horrible as my daysy doesn’t even sync half the time with the app... if I would’ve known that I would’ve gotten the first series.

Love this for tracking my cycle. It’s easy to use and love best it syncs with my phone. My only complaint is that it takes a while to read your temperature. This would not be a big deal if I didn’t have a small infant who wakes up in the night to feed and I have to take my temp before getting up to feed him.

I love my Daysy I’ve told all my friends!! I’m so happy being off the synthetic hormones of the Pill

Malfunctioned for the 1st month, had to speak to people several times for troubleshooting. Still don’t know if it works consistently or correctly so am still using backup methods. Feel as if a new product should have been offered.

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.

I honestly do love Daysy. I give it a 3 because while the device itself is awesome, the app is still not great. A little glitchy and too often when I try to sync it is says try again later or cannot be synced at the time. I love knowing based on the light my prediction/status, but would love the ability to see the data on the calendar and use it to its fullest.

Product works great the app can be very buggy.

Overall pretty accurate, I’ve only been using it a couple months. Takes the guesswork out of taking temps and charting.

Daysy does what it says it does. As the company explains, at the beginning there are more red/yellow days, but as you are consistent in taking your temperature it learns your cycle and more and more green days appear. Perhaps a little frustrating to wait, but I appreciate that the Daysy values accuracy over speed/convenience. I have not had problems with the daysyview app (as many people seem to be having), it syncs, has a calendar view as well as a line graph of the data, space to add notes and track fluids (I'm not that interested, but I'm sure some people are) and is easy to use. When syncing data make sure to have the app open, push the sync button on the phone and then double click the daysy...I haven't had any trouble with syncing. I am a satisfied customer and grateful for the ease this technology brings.

Daysy has helped me get more in tune with and respectful of my own body and its needs. It saved me from hormone-induced depression while also helping me prevent unwanted pregnancies!

I love my Daysy! Sometimes I have a hard time getting my measurements to sync with DaysyView, though. Daysy really helped me learn about my body and how cycles work.

I’ve learned so much about my cycle in the few months I’ve had daysy, it’s such a relief knowing I’m not masking my pms symptoms with a pill and that there are zero negative side effects

Customer service is amazing. The site is straight forward, and any questions you may have a customer service representative will be able to help. They know how to navigate through the online site and the app. Everyone I've spoken to have been patient and care about how comfortable you feel using the product.

It is not user friendly and it’s hard to go back and change input if you registered ovulating and you’re not.
