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!

Helpful info, needs a little more


This info is very amazing and having it all in one place is great. My suggestion is to allow for setting the number of bleeding days rather than defaulting to seven. My cycle is only 22 days, which I set in the app, however, I only bleed for four days and ovulate on day six, not day eight like the default on the app. I'm sure this affects my hormones and setting the days more accurately would give me a clearer picture.

Great app! Horrible UX/UI


Content is amazing. I love this idea! Now I know what version of myself I'll be putting up with in my head all day!

BUT, I have to say, the UX/UI is absolutely terrible. I hope they invest in renovating the design. I hate feeling like apps for women are always cheesey, sub par, less intuitive, etc

I work in the tech industry and would love to help source designers if this is what is holding the design back...

Content is GREAT

I've learned so much- and also get really good info from following hormonology on twitter.

I love that I can write notes for each day and they're saved month to month, so I can know what to expect in each part of my cycle.
