Daysy sync is trash This app is horrible. Yes the tracking feature is cool when I can get my Daysy to SYNC! Which is impossible 95% of the time. Yes the blue tooth is on, yes I have reread the instructions 80 times, yes the notifications is on, yes I let the Daysy fall asleep then try to resume syncing. It takes me having to log out of the app entirely and sometimes uninstall then reinstall just to get a reading. And that sync button in the upper right hand corner is completely useless. It does nothing. No one wants to do that in the morning every day because it won’t automatically sync or even manually sync for that matter.

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.

I already loved Daysy because she is a… I already loved Daysy because she is a great form of natural birth control and I've only had great experiences with her. The customer service team on Daysy just makes having her even better. I've only ever had amazing communication with them; they're so timely, kind, and mindful. I love supporting this company and the amazing product.

Very expensive mistake to purchase. I have been beyond disappointed with the Daysy I purchased. I waited very long to get the new version (their website said the wait would be much less than it actually was which screwed up our family planning with our doctor that we started based on the websites indicated ship date). It takes at least two tries to take my temperature every morning and each try takes over two minutes. It very rarely actually syncs with the app. I've contacted support several times and they've been rude every time. I am not the only one having issues but they still make it feel like it's my fault. Definitely not worth what they charge for it! I was going to return it but decided to give it a chance. Big mistake. I also take thyroid medication which apparently screws up the readings but isn't mentioned anywhere in the information so a doubly worthless version expensive device.

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.
