The Hormone Horoscope App "Lite" 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 cycle. That's it!

Life Changing

I’ve been using this app for a little over a year after a friend recommended. It has helped me better understand, track, plan, and improve all aspects of my health. As someone diagnosed with PMDD, I had already identified my physical, mental, and emotional health drastically deteriorating consistently the week prior to the start of my period. However this app has helped me understand all the other symptoms of my hormones in between, which I didn’t recognize as symptoms. Simply understanding what is going on with my body has helped me be more cognizant of my mood and interactions, but also knowing what to expect and how to lessen symptoms has been life changing. The app forecasts are pretty simple and basic, but referencing it when I notice changes and/or planning events/trips is SO convenient, not to mention reassuring. I’ve become more self-aware; accepting and/or changing/improving where I can relating to patterns in my behavior. Thank you 💕💕✌️

So Helpful

Pretty sure I’ve never written a review of an app before, but wow, this has been EXTREMELY helpful to me having a daily explanation of what is happening with my hormones. My cycle is about 24 days so I feel like im up high then down low very often and it’s been very comforting to finally understand and have some science behind my moods as a way to try to detach myself from them a little more easily. I reallllly appreciate this app so much. Thank you thank you.

Super helpful app!

I am absolutely obsessed with this app. It is incredibly useful to be able to see the upcoming ups and downs of my cycle and to be able to plan accordingly. Simply becoming aware of what is happening inside helps TREMENDOUSLY to make me feel less at a loss as to why I feel the way that I do any given day. It helps me feel a bit more in control, in a way, and I don’t spend any time worrying about how I feel and why.

I think it could be improved by customization of choosing which days one stops bleeding and ovulates, for those who know. I have only used this app one month so far but I felt I may have ovulated a day earlier than it stated. Also, the general feel of the app could be a bit more streamlined and fun to look at.
I loooove that there is no ads!
