I was on hormonal birth control for over 13 years, and when I finally decided that it was time to ditch the hormones, it was important to me that I found a natural way to help avoid pregnancy.

While many rely on period-tracking apps, they aren’t always accurate, depending on when you ovulate and your cycle length. I knew I needed an effective, precise tool, so I chose Daysy.

What is the Daysy fertility tracker?

Daysy is part basal thermometer and part app. Daysy is a small device you use to take your temperature first thing in the morning. 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.

Recent Daysy updates

Because this Daysy review was written a few years ago, Daysy and its accompanying app have had significant updates. Click on the section below to read the latest about the Daysy fertility monitor.

You may be wondering, how long does it take Daysy to work?

While Daysy can “work” right out of the box, the feedback and data you receive won’t be custom to your unique menstrual cycle. What makes Daysy different from other basal body temperature thermometers is its built-in algorithm that learns your cycle, and you’ll see more customized readings the longer you use it. 

I suggest using Daysy consistently for at least three months for the best representation of your fertile window.

By using Daysy over a more extended period, Daysy will predict when you’re fertile and ovulating and when you’re not. The longer you use Daysy, the more insight and accurate feedback you’ll get when viewing data in the app or on the monitor.

2019 update: Daysy 2.0 released!

As of late March 2019, Daysy 2.0 will replace the original Daysy outlined in this post. I was lucky enough to test Daysy 2.0 before it hit the market, and 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 to save on your order. (That link will take 10% off your order automatically!)

2020 update: DaysyView app becomes DaysyDay

As of December 2020, the Daysy app received a significant facelift.

DaysyDay is an entirely new app designed to help you track your cycle and basal body temperature and log your period, intercourse, cervical fluid, notes, and more.

When you open the app, you’ll see it’s much more intuitive than its predecessor, with a cleaner, more modern interface. Check out some screenshots below.

More recent Daysy updates

The 2020 update of Daysy was certainly the most robust and helped Daysy become an easy, integral part of BBT users everywhere. Even more recently, I’ve seen that Daysy offers some newer updates I hadn’t seen before, including:

  • Two-year warranty
  • Free partner app (to help your partner keep track of your cycle, too)
  • Experts are available by phone and email to answer any questions
  • Free shipping and no subscription costs (yay!)
  • Discount increased to $10 (you can save by clicking here)

How to use Daysy

As I mentioned above, use Daysy right when you wake up after at least four hours of consecutive sleep. Don’t use it after you get up to go to the bathroom, check your phone, or kiss your partner good morning.

Timing is crucial because Daysy measures your body’s resting temperature, and it should capture that number in its most natural state for the most accurate reading.

If you are menstruating that day, let your Daysy know by holding the center button until the purple light shows. Recording your menstrual cycle is essential for your Daysy to identify it and can affect how she learns your cycles.

What do the lights on Daysy mean?

After you take your morning reading (about 30 seconds), your Daysy light will turn red, yellow, or green. Here’s what those lights mean.

  • Red light: you are fertile; use an additional barrier method to prevent pregnancy. We prefer these super-thin vegan condoms if we are not actively trying to conceive.
  • Yellow light: treat these days like red days; Daysy is experiencing cycle variations and is still learning your cycle.
  • Green light: you are not fertile and can enjoy sex with your partner without another protection method.

From there, you can sync your daily reading to the Daysy app to chart your temperature and cycle changes. I sync to the app every few days just to be safe.

Again, it takes about three months for Daysy to learn your cycles, so don’t get discouraged if you see many red and yellow days pop up over the first ninety days. It’s essential to ensure your partner is on the same page as you throughout this process!

How effective is Daysy?

Planning for or avoiding pregnancy is a big deal, and you should have a device that puts your mind at ease. The developers of Daysy are pioneers in the femtech industry and have over half a million fertility trackers and monitor users.

Did you know Daysy 2.0 won the 2019 Red Dot Design Award? Learn more about what makes Daysy so great.

It’s important to note that Daysy is a fertility calculator vs. traditional birth control like the pill. Daysy uses no synthetic hormones or chemicals, and you can decide in a moment whether you want to try for a baby.

If you decide to start a family, Daysy can help you chart your most fertile days and give you more insight into when your chances of pregnancy are highest. Rest assured that Daysy’s effectiveness is definitely in your favor.

What I love about Daysy

  • 100% natural – there are no synthetic hormones or pills of any kind
  • It 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 was added for Daysy 2.0 as of March 2019
  • Remaining patient throughout the initial learning cycle

Final thoughts and wrapping up my Daysy review

Daysy is genuinely one of the best investments I’ve made in my health. She allows me to feel empowered and secure in my sexual wellness. The physical self-care changes (more energy, less anxious feelings, no more brain fog) I’ve felt in just a few weeks of choosing Daysy over my IUD are incredibly eye-opening and worth every penny.

The Daysy fertility tracker is hands-down my favorite birth control method to date. Use condoms (we love this brand best after trying many) on red and yellow days if you aren’t trying for a baby!

It has empowered me to regain control of my 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 be your choice. Please note I suggest working with a functional doctor or midwife while transitioning from hormonal to non-hormonal birth control, as this experience can be different for everyone.

    Hi I’m Erika. I have been using a copper IUD for about 3 years. I will like to start using Daysy. I was wondering if I could use both methods for the first 90 days while Daysy learns my cycles. I’m kind freaking out about getting pregnant so I want to be as safe as possible. Will the copper IUD interfere with my temperature and the reading???

    • CARLEY says:

      Hey Erika!

      I’ll give you my opinion as someone who had an IUD and switched to Daysy. Personally, I wouldn’t. I’d wait to start Daysy once your IUD has been removed (should you choose to get it removed) so Daysy has a chance to learn your natural cycles without interference of any kind. Keep in mind, Daysy is effective when used correctly, so just make sure to use condoms on the days you’re red or orange and follow her prompts! If you’re still concerned or curious, you can email Daysy at info(at)usa.daysy.me to ask what they’d recommend! 🙂

      Hope this helps! xx

    I’m a little on the fence on buying this, because it’s so darn expensive ????????
    And I’ve been curious to know if I when I buy it? Should i start using it when i get my IUD removed. Because I’ve had it on for 2 years now and haven’t gotten a period at all. Should i just wait until my cycle begins?

    • CARLEY says:

      Hi!

      I totally get the hesitation around price. Be sure to check with your insurance company as the Daysy could be covered up to 60%! As far as when to start using it, I personally started using it as soon as my IUD was removed but note that your first “period” off of birth-control is just your withdrawal bleed so you don’t need to tell your Daysy it was a true period. According to Daysy, “The first bleeding after coming off hormonal birth control is a withdrawal bleeding and must not be entered as your period. Please make sure your first menstruation entry is on the first day of active bleeding and flow.”

      Hope this helps!

    • CARLEY says:

      Hi Chloe! Daysy will tell you your daily BBT and use her unique algorithm to predict your daily fertility status. Hope that helps!

  • Katinka says:

    Hello and thank you for your support. My question is :
    You can use this only if you have iphone 7 and above?
    I have samsung , is that mean I can not use Daysy because there are no application for it? Thank you!

    • Chynna Benton says:

      Hi Katinka!

      Thank you so much for asking. This is a great question!

      There is an app on the Google Play Store called “DaysyView”, so I believe you should be able to use Daysy with your Samsung phone. 🙂

    Helloo,
    I’ve been birth control for nearly 10 years, the pill, 3 implants and an iud which only lasted me 7 months! My iud was embedded into a muscle, therefore I had to have surgery to have it removed, it was working so well but I’m a little worried to have it again!
    I came across daysy online and did some research, your website has helped me a lot, I’m 99% sure I want to try it!
    My partner is super supportive and we’re both not ready to have children just yet!
    I just have a few questions if you could answer then that would be great!

    Would you recommend I wait for a period before I start using daysy since coming off the iud?

    Does the daysy tell you when you’re ovulating? If I have unprotected sex 5 days before I ovulate will I know I’m safe not to get pregnant?

    Thanks so much!

    • chynna says:

      Hi Libby,
      Sorry to hear about your struggles! As Daysy is only a temperature monitor, you can feel free to start using it any time! For the question about fertility, nothing is 100% but the more you use Daysy the more accurate it will be to judge when there is risk.
