The Hormone Horoscope App "Pro" is an easy-to-use menstrual cycle tracker that gives you something no other app can: The daily Hormone Horoscope--a forecast that tells you what your mood, energy, love life, spending habits, sleep quality, health and much more will be based on the levels of your hormones for each day.

For example...

On Day 7 of your monthly cycle, rising estrogen makes you more upbeat, energetic, confident, adventurous and creative--making this a great day to tackle a big task, take a trip or brainstorm.

On Day 18, rising progesterone saps your pep and makes you quieter and more cautious--making you prefer low-key activities close to home.

On Day 24, plunging estrogen can cause a bit of moodiness and irritability--but, you're also burning up to 30% more fat when you exercise.

As three key hormones (estrogen, testosterone and progesterone) rise and fall during your cycle, research shows they impact your brain and body in a wide variety of ways.

Because your hormones repeat the same up and down pattern every cycle, the effects your hormones have on you also repeat the same way cycle after cycle--making your moods, energy and more easy to predict!


Tap the Settings tab, then input a couple of details about your menstrual cycle. That's it!

Researched Based Women’s Wisdom

I set out to learn about the follicular and luteal phases and have used the free app for over a year now to help me learn about my cycle and embrace it. I found the app as part of my own decision to be kinder to my body and care for it after a lifetime of actively avoiding my natural hormone cycle, hating to HAVE to have a “period,” and wishing my ovaries would fall out.

Each day of the cycle, Gabrielle offers a keen insight as to what you may be experiencing emotionally and it is spot on! Combining maximum self-awareness with this research-based knowledge about the hormone cycle, I feel more connected to my “wise woman,” empowered to embrace my inherent power, and grateful to my whole reproductive system.

I can add notes to the days and have noticed patterns that I can use to expect certain feelings and plan for them, or notice them and feel great knowing that based on those symptoms, I am at a certain part of my cycle. At the very least, USE the free app to get in tune with yourself, BUY this app as the smallest thank you to the author for her dynamic work. In my mind, she’s the next Dr. Christiane Northrup!

Thankful but confused

I was excited that so far this application has helped me keep track of when my period is due as well as my fertile days. With PCOS I have never been sure when my period would start unless I was taking birth control pills. Those pills aren’t really helpful when trying to conceive. I did read, in the beginning, all of the information about how I would act, feel, etc. Now i skim it to see if I should put my husband to work overtime in case I could ovulate that month. I think there is an issue with too much information & I really just want the calendar & a small description of what is going on that day.

Should have started using this a long time ago

This app has helped to clarify so much for me. I even bring in the information I learn from it into my doctor’s and therapist’s appointments. The paid version is much better than the free btw. More detailed descriptions as well as a less “hey girls” approach. I do wish the language would be less gendered at times, as I am nonbinary.
