Even though it has ONE button. It’s hard to make it work, there are days that I would think it recorded my temperature and it wouldn’t. Disappointed since I paid a pricey cost.

I've really enjoyed that Daysy automatically stores my temperature. And that's honestly the only up side in comparison to Natural Cycles. I've been using both only because Natural Cycles uses a basic thermometer (to the correct decimal) and is difficult to manually record my temp from.
These are the perks I wish Daysy had that Natural Cycles does:
- Take LH test into account. My ovulation date is still jumping around a bit (as opposed to Nat. Cycles) because I can't give it this information.
- Easily exclude a temperature later if you realize you didn't sleep well, feel sick, or are hung over. It can cause irregular measuring if I skip measuring for these reasons and get out of a rhythm.
- Automatically sync data to the cloud: it can be annoying to sync when it fails several times. (Not applicable to Nat. Cycles).
- Show more data on the trend overview instead of requiring the user to scroll. (Rotate to landscape).
- Have alerts for things from "you're going to start PMSing" and "It's time to do a manual breast exam" to educational posts about how a woman's cycle works and how the app is calculating things.
- Record things like PMS, mood, and sex drive.

Not easy to use. Very disappointed. Very frustrating. Wish that I could return it but it is past the window. I didn’t open it right away due to a busy life hahahaa so by the time I realized that this product was a waste for me it was too late. Oh well!

I have an infant, and it isn’t possible for me most days to take a basal temp that takes that long to register before getting my son. Also I rarely get three straight hours of sleep. Doesn’t seem like achievable birth control for me right now which is too bad.

So many bugs I’m constantly troubleshooting.

My Daysy is a quick and easy way for me to ensure I have safe sex. I don't know what I would do without it.

Daysy has the best customer service! They are always very quick to respond to any issues. I’ve been using Daysy for three years since I got off the pill. My first Daysy got damaged and they sent me another one in the newer version as soon as I sent the old one in. Highly recommend!

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.

It never worked and I wasn't able to get a refund for it. I was very disappointed with the daysy.

I have had an absolutely horrible experience with daisy. Daysy didn't work, is not worth the money and the customer service is horrible! I tried to make contact with daysy to troubleshoot and they were not willing to help me, would not give me a refund for my defective product and insisted on emailing me rather than calling me. Needless to say, I'm extremely frustrated to have a defective product that I paid hundreds of dollars for.

I couldn’t make it work and I should have reached out for help to fix it but I was just trying to cope with my miscarriage I never made the time

The item did not work for me and They have refused to give me my money back.

Always so patient and helpful with any request, concern, or question.

It never syncs properly with the app. You have to continue doing it over and over till it finally works. When I input information half the time it doesn't save. It takes about 2 minutes for it to take your temperature. For the price, it's just ridiculous that it all works so poorly.

It's been so empowering to learn my unique cycle without hormonal junk in my system. Daysy is easy to use and understand. A minute in the morning is the best decision I've made in my journey from TTA to TTC. I recommend Daysy to all my friends! I'm never going back on hormonal birth control again!
