Whether or not you’re trying to conceive, using Daysy to monitor and track your fertility status is an effective way to plan for or avoid pregnancy. Learn more through my full Daysy review below.

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 the actual day you ovulate and your cycle length. I knew that I needed an effective and accurate tool, and that’s why I chose to use Daysy and my Daysy discount code.

2020 update: DaysyView app becomes DaysyDay

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

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

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

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.

If you are menstruating that day, make sure to let your Daysy know by holding down the center button until the purple light shows. The recording of your menstrual cycle is essential for your Daysy to identify and affects how she learns your cycles.

What do the lights mean on Daysy?

After you take your morning reading, which takes about thirty seconds, your Daysy light will turn either red, yellow, or green. Here’s what those lights mean.

  • Red light: 你是 fertile, use an additional barrier method to prevent pregnancy. We prefer these super-thin vegan condoms if we are not actively trying to conceive.
  • 黄色灯光: 处理这些天 就像红色的日子; 这意味着Daysy正在经历周期变化,并且仍在学习你的周期。
  • 绿灯: 你是 不生育 并且可以在没有其他保护方法的情况下享受与伴侣的性生活。


同样,Daysy大约需要三个月的时间来了解你的周期, 所以,如果你在头90天里看到许多红色和黄色的日子突然出现,不要气馁。在整个过程中,确保你的伴侣和你在同一页上是至关重要的!

What I don’t love about Daysy

  • 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 授权 and secure in my sexual wellness. The physical self-care changes (more energy, less anxious feelings, no more brain fog) that I’ve felt in just a few weeks from choosing Daysy over my IUD is so incredibly eye-opening and worth every penny.

The Daysy fertility tracker is hands-down my favorite birth control method to date. Just make sure to 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 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.

  • 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???

    • 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) 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?

    • 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!

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

  • I really appreciate your useful and very persuasive explanation!!! When my teenage daughter was ready to become sexually active with her boyfriend, she begged me to let her go on the pill. Instead I taught her the basics of FAM and bought a fertility monitor for her. At first she was terrified by the idea of having unprotected sex and really worried about getting pregnant in high school, but websites like yours helped me to persuade her that FAM is much better birth control than condoms or the pill. Giving her an introduction to FAM before her first time with her boyfriend was also a great mother-daughter experience for us and really was what gave her the the little push she needed to get over her shyness about her body and become sexually active. She now is completely comfortable having unprotected sex with her boyfriend on her “green” days, and she promises me they are super careful with any kind of P-in-V on her “red” days. This may not work with all teens, but they are both straight-A students and really responsible, and I can tell FAM has really strengthened their relationship. You are a great role model for responsible teens!

    • 哇,这真是一个精彩的故事!我喜欢你和你女儿分享的开放,你教给她的东西是如此无价。谢谢你的客气话,我很高兴FAM和生育率监测工作顺利进行!


  • 谢谢Carley。我再怎么强调都不为过,帮助你的女儿为自己的性取向和生育能力制定一个健康的生活计划是多么重要,而她仍然有与母亲在家生活的支持和指导。如此多的女孩陷入性困惑、不确定和冲突。我的女儿应该有一个更积极的经历,这对我来说真的很重要。当她开始和男友约会时,我并没有等她来找我谈性问题——我先和她提起这个话题。起初,她坚称自己太小了,不能开始性交,她“从未”想要孩子。我坚持让她开始使用Daysy和learning-FAM,这就是我说服她性活跃,不要使用避孕套或避孕药的途径。与她讨论了几个月,但当她最终与男友有了第一次性体验时,这是有计划的,是安全的,是在我的鼓励下(那天晚上我们家的其他人都出去吃比萨饼和看电影了,所以她第一次可以在卧室里),而且没有任何障碍或激素避孕。
    Practicing responsible FAM has really formed a strong bond between my daughter and her boyfriend, and I can see that she is increasingly accepting of her fertility as the next step in expressing their intimacy. As you say, Daysy gives my daughter “full control over whether or not you’d like to try for a baby within a moments notice.” His mom and I have discussed their relationship and are ready and supportive for them to take that next step. My daughter is in her senior year of high school now, and he is a freshman in the local college, and she and I have discussed several times the special magic of “red day” sex both physically because of her heightened responsiveness when she is fertile and emotionally as a true expression of both partners being open to the possibility of making a baby together. Educating her that most women don’t get pregnant the first time they “try” to get pregnant and that almost all women need at least a few months to get pregnant has definitely increased her receptiveness to being intimate with her boyfriend on her “red” days. I am really looking forward to when they begin using FAM for TTC instead of TTA.

  • 您好,谢谢您的支持。我的问题是:
    只有当您有iphone 7及以上版本时,才能使用此功能?

    • 嗨,卡廷卡!


      Google Play商店中有一个名为“DaysyView”的应用程序,所以我相信你应该可以在三星手机上使用Daysy。🙂
