What is the Daysy fertility tracker?
Daysy is part basal thermometer and part app. Daysy is a small device that you use to take your temperature the moment you wake up orally. Based on your temperature reading, you will receive feedback on whether or not you’re fertile. That morning reading is your fertility status for the next 24 hours.
From there, you and your partner can determine the best course of action for the day based on your intention – to get pregnant or to prevent pregnancy.
What makes Daysy different from other thermometers is that it has a built-in algorithm to learn your cycle and you will begin to see more customized readings the longer you’ve used it.
Bottom line: by consistently using Daysy over a more extended period, Daysy will start to predict when you’re fertile and ovulating, and when you’re not.

2019 update: Daysy 2.0 released!
As of late March 2019, Daysy 2.0 will be replacing the original Daysy outlined in this post. I was fortunate enough to test out Daysy 2.0 before she hit the market, and let me tell you, I’m thrilled with her new updates!
Here’s what you can expect with Daysy 2.0:
- Bluetooth capabilities (no more plugging Daysy into your phone to sync data)
- A rechargeable battery
- The ability to edit menstruation input via the button on Daysy
- More robust housing and a flexible neck
In addition to the updates on the physical Daysy, the app has received a beautiful refresh that promotes ease of use and more accessible data about your cycles. And of course, use my daysy discount code and save 25% on your order.

How to use Daysy
Like I mentioned above, it is imperative to use Daysy right when you wake up after a night of at least four hours of consecutive sleep. Not after you get up to go to the bathroom, not after you check your phone, not after you kiss your partner good morning.
The reason why the timing is so crucial is that Daysy measures your body’s resting temperature, and that number should be captured in its most natural state to ensure the most accurate reading.
Also, if you are menstruating that day, make sure to let your Daysy know by holding down the center button until the small purple square pops up. That is essential data for your Daysy to identify and will affect how she learns your cycles.
After you take your morning reading, which takes about thirty seconds, your Daysy light will turn either red, yellow, or green.
- Red: you are fertile, use an additional barrier method to prevent pregnancy. We prefer these super-thin vegan condoms.
- Yellow: handle these days like red days; they mean that Daysy is experiencing cycle variations and is still learning your cycle.
- Green: you are not fertile and can enjoy sex with your partner without another method of protection.
From there, you can choose to sync your daily reading to the Daysy app to chart out your temperature and cycle changes. I sync to the app every few days!
Again, it takes about three months for Daysy to learn your cycles, so don’t get discouraged if you see a lot of red and yellow days pop up over the first ninety days. It’s essential to make sure your partner is on the same page as you throughout this process!
Is Daysy effective?
Yes! Daysy is effective.
It’s important to note that Daysy is a fertility calculator vs. a traditional birth control like the pill. With Daysy, there are no synthetic hormones, chemicals, or unwanted side-effects and full control over whether or not you’d like to try for a baby within a moment’s notice.

Should you decide to begin a family, Daysy can be used to chart out your most fertile days and give you more insight into when the potential for pregnancy is at its highest. Rest assured that the Daysy effectiveness is definitely in your favor.
What I love about Daysy
- 100% natural – there are no synthetic hormones or medicine of any kind
- Empowers me to reconnect with my body’s natural cycles
- One-time payment vs. monthly prescription bills (like when I was on the NuvaRing)
- Super user friendly and easy to use
- Easy to figure out whether you’re fertile or not
- Varying settings in the app depending on if you’re trying to get pregnant or not
What I don’t love about Daysy
- Remembering to take my temperature immediately upon waking up (I’ve started placing it on top of my phone to remind me to do it first thing)
- No Bluetooth syncing. You do have to plug it into your phone (with the extension piece for iPhone 7 and above), but it’s really not that complicated Update: Bluetooth capability has been added for Daysy 2.0 as of March 2019!
- Remaining patient throughout the learning cycle
My final thoughts on Daysy
The Daysy fertility tracker is hands-down my favorite birth control method to date. Just make sure to use condoms (we love these!) on red and yellow days if you aren’t trying for a baby!
It has empowered me to take back control of my own body and begin to understand how I feel without synthetic hormones. I feel confident and secure while using Daysy, and it has opened up my relationship to some essential topics, including how I’m feeling during different phases of my cycle.
If you’re considering changing your hormonal birth control, Daysy might just be the right choice for you. Please note, I do suggest working with a functional doctor or midwife while navigating the transition from hormonal to non-hormonal birth control, as this experience can be different for everyone.

A note from Carley
Please know that my experiences are simply that, my experiences.
I believe women should choose a birth control method that works correctly for their bodies and realize that Daysy might not be the right choice for everyone. Thankfully, it was for me!
