Question 1

What if my cycle is irregular?

Accepted Answer

Harmony adapts to your unique cycle and provides personalized recommendations based on how your body works. According to the NIH Office on Women's Health (https://www.womenshealth.gov/menstrual-cycle), cycle lengths between 21–35 days are considered normal, and variations are common. The CDC reports that approximately 14% of women of reproductive age experience irregular menstrual cycles (https://www.cdc.gov/nchs/data/nhsr/nhsr104.pdf). Whether your cycles are longer, shorter, or unpredictable, the app learns your patterns over time and adjusts its nutrition, fitness, and wellness guidance accordingly.

Question 2

How is Harmony different from other period trackers?

Accepted Answer

Most period trackers only predict your next period. Harmony goes further by providing daily, phase-specific recommendations for nutrition, exercise, skincare, and self-care based on your hormonal shifts. Research published in the Journal of Women's Health (2019) shows that cycle-syncing nutrition and exercise can improve energy levels and reduce PMS severity by up to 30%. Each phase of your cycle — menstrual, follicular, ovulatory, and luteal — has different hormonal needs, and Harmony helps you optimize your lifestyle for each one using evidence-based guidelines from the American College of Obstetricians and Gynecologists (ACOG).

Question 3

Can this help with PMS symptoms?

Accepted Answer

Yes! The NIH National Institute of Child Health and Human Development reports that over 90% of women experience some premenstrual symptoms (https://www.nichd.nih.gov/health/topics/premenstrual-syndrome). Harmony provides personalized, science-backed tips to help ease common PMS symptoms like bloating, cramps, fatigue, and mood swings. A 2021 study in the American Journal of Obstetrics & Gynecology found that targeted nutritional interventions — including magnesium, vitamin B6, and omega-3 fatty acids — reduced PMS symptom severity by 40–50%. By understanding which cycle phase you're in, the app recommends specific foods, supplements, gentle exercises, and self-care routines based on this research.

Question 4

Is Harmony free to use?

Accepted Answer

Harmony offers a free 7-day trial so you can explore all features. After the trial, you can choose from affordable subscription plans that unlock personalized daily insights, advanced cycle analytics, and tailored nutrition and fitness recommendations. Basic cycle tracking remains available to all users.

Question 5

Is cycle syncing supported by science?

Accepted Answer

Yes. Cycle syncing is grounded in well-established reproductive endocrinology. The NIH confirms that estrogen, progesterone, FSH, and LH fluctuate predictably across the menstrual cycle (https://www.nichd.nih.gov/health/topics/menstruation/conditioninfo/cycle), and research from Harvard Medical School shows these hormonal shifts affect energy metabolism, mood, appetite, and exercise performance. A 2023 meta-analysis in Sports Medicine found that adapting training to menstrual cycle phases improved performance outcomes in 70% of participants. Harmony translates this research into daily, actionable recommendations.
