About this app

Owned and built by women, and used by more than 750,000 women. Your data is not sold to third parties and is used only to give you the forecasts and insights you ask for.

Moody Month is a hormone and cycle tracker for every life stage: regular, irregular and changing cycles, perimenopause, pregnancy, postpartum and life after a loss. It gives you a short daily hormone forecast: a read on what your hormones are likely to be doing today and what tends to help, based on your cycle or life stage and what you log.

Moody Month is a companion tool, not a medical or diagnostic one. It is not a contraceptive.

WHO IT IS FOR
- All cycles: irregular, long or short. Moody works from what you log, not from an assumed 28-day cycle.
- PMS and PMDD. Track your mood and symptoms every day and see how they change in the days before your period.
- Perimenopause and over 40. Log hot flashes, sleep and mood with or without a period. No period? Switch to no cycle mode.
- Pregnancy. A pregnancy mode about you, not just the baby: how you might feel today and this week's changes.
- Postpartum. Day-by-day forecasts for your physical and emotional recovery, after a vaginal birth or C-section, breastfeeding or not. Support after a pregnancy loss is included.
- No periods or cycle? You can still track your moods and symptoms alongside useful wellbeing advice.

EVERY DAY IN MOODY
- Your daily hormone forecast
- Period predictions
- Mood and symptom tracking
- A mental health score you can follow over time
- Patterns and trends in what you log
- Nutrition, movement and mindfulness tips for each phase

MOOD, ENERGY AND SYMPTOMS
Log mood, energy, sleep and symptoms in a few taps, and compare how you feel with last cycle. Moody shows how your logs line up with your cycle phase, such as follicular or luteal, so you can see what is typical for you. For many women, mood and energy lift through the follicular phase as estrogen rises, and in the days before a period, when estrogen and progesterone fall, you may feel more sensitive or low.

ALSO IN THE APP
- Ovulation predictions
- Programs for PMS, stress, sleep, bloating and more
- Audio and text journaling
- Share how you're doing with your friends
