Wouldn't it be great if we had a crystal ball that predicted exactly how each day was going to pan out?
Enter the Hormone Horoscope app, which offers women a precise rundown of how they will feel emotionally, physically and mentally throughout each day.
Claiming to give you an accurate prediction of your "mood, energy level, cravings, brain skills, chattiness, pain sensitivity and desire for romance", the app uses new technology to track your mood depending on your monthly cycle.
For example, if you are on the first day of the third week of your cycle, you might experience “levels of estrogen and testosterone nose-diving, which can trigger ‘pre-PMS’.”
Founded by health journalist Gabrielle Lichterman, who also wrote the book 28 Days: What Your Cycle Reveals about Your Love Life, Moods and Potential, the app is “the world’s only horoscope based solely on your hormones”. The app was developed using research from hundreds of scientific studies which found that women's moods are dependent on how their levels of oestrogen, testosterone and progesterone vary throughout their monthly cycle.
Free to download, you simply have to tap in some information such as the length of your cycle and the day you are currently on, and let the app work its magic to give you a daily “hormone horoscope”.
And the app doesn't just tell you how you will feel on a given day - it can also give you tips to make the most out of your emotions.
The website claims the app will “show you how to predict these hormonal influences so you can capitalize on the hormonal benefits and overcome hormonal challenges to make every day better.”
