# EvaShark
> EvaShark is a cycle-synced AI wellness app for women. It helps you practice cycle syncing — aligning training, nutrition, recovery, and daily habits with your menstrual phases (menstrual, follicular, ovulatory, luteal) — so you work with your hormones instead of against them.

EvaShark (product codebase: Femform) is a female performance training and hormonal health app available on iOS via TestFlight. Primary keyword focus: **cycle syncing** / cycle-synced wellness.

## What is cycle syncing?

Cycle syncing is the practice of adapting workouts, meals, sleep, skincare, and productivity to the four phases of the menstrual cycle. Estrogen and progesterone rise and fall across the month, which changes energy, recovery capacity, metabolism, mood, and cognitive strengths. EvaShark turns that science into daily, personalized guidance.

## Product features

- **Smart period & phase tracking:** Confidence-based period predictions, a visual four-phase calendar, and support for irregular cycles and pregnancy (matrescence mode).
- **Cycle-optimized workouts:** AI-generated daily training plans that adjust for cycle phase, fatigue, cramps, fitness level, and location (home or gym). Includes foundational movement education.
- **Intuitive fueling & nutrition:** Food logging, metabolic check-ins, phase-aware nutrition guidance, and a weekly diet / weekly buys planner — not restrictive dieting.
- **Barcode product scan:** Scan food, beverage, and cosmetic barcodes for health scores, additive risk insights, dietary compliance (including halal and other claim badges), and healthier alternatives.
- **Daily check-in:** Log energy, mood, symptoms, sleep, menstrual flow, libido, digestion, and lifestyle factors; build streaks that improve personalization.
- **Empathetic AI wellness coach:** 24/7 cycle-aware chat for stress, nutrition, training pivots, and lifestyle choices (privacy-gated AI consent).
- **Clinical & trend insights:** Symptom pattern analysis, performance trends, and reports that surface correlations from your logs.
- **Body Wisdom library:** Curated, citation-backed articles on hormones, fitness, nutrition, mental health, relationships, and self-care.
- **Community wall:** Shared wisdom and peer support for women reclaiming biological literacy.
- **Privacy-first architecture:** Health data is not sold; AI sharing is opt-in. Wellness insights are informational, not medical advice.

## Who it is for

Women who want to balance hormones, build strength, reduce burnout, and stop following one-size-fits-all fitness or diet plans that ignore the infradian rhythm. Goals supported in-app include build strength, balance hormones, tone & sculpt, lift heavy, HIIT, muscle, endurance, mobility, and stress reduction. Conditions-aware onboarding covers PCOS, endometriosis, thyroid/Hashimoto’s, PMDD, fibroids, perimenopause, postpartum, insulin resistance, and iron deficiency anemia.

## How cycle syncing works with EvaShark

1. Track your period and let EvaShark learn your unique cycle length and phase timing.
2. See which phase you are in: menstrual (winter), follicular (spring), ovulatory (summer / power phase), or luteal (fall).
3. Receive phase-matched workouts, fueling cues, recovery guidance, and product scan insights.
4. Log daily signals so predictions and coaching become more personal over time.
