Can't revise menstruation data from >3 days prior Your product doesn't allow you to go back to revise menstruation data if it has been 3 days since the entry. This makes it extremely frustrating if you've already logged multiple months of data, and now have to do a factory reset in order for Daysy to accurately track your cycle. I have contacted Daysy about this issue, and have not been given any way to fix this issue without reseting the device and starting its tracking from day 1. I haven't found any cases online of other customers who have been able to resolve this issue either.

Literally the biggest waste of money on… Literally the biggest waste of money on the entire planet. Doesn't sync with your phone, takes forever to take your temperature and straight up doesn't work. I have reached out to customer support multiple times and they have told me to download beta versions of their app and all different types of solutions and nothing ever works. Absolutely garbage. Don't waste your money.

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.

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!

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!!
