BAESIL — CYCLE TRACKING ROOTED IN SCIENCE

Baesil is the only cycle tracking app that tracks all of YOU!

Most period trackers just count days. Baesil tracks how your hormones affect your energy, strength, mood, and performance — then tells you exactly what to eat and how to train at every phase.

🌿 BBT CHART & OVULATION TRACKING
• Basal body temperature (BBT) chart with automatic thermal shift detection
• Ovulation window prediction with real-time BBT confirmation
• Emergency contraception (EC) hormone adjustment — the only tracker that accounts for levonorgestrel's delay effect on ovulation
• Cervical mucus and symptom correlation

⚡ CYCLE PHASE RECOMMENDATIONS
• Menstrual phase: rest, iron-rich foods, reduce intensity
• Follicular phase: peak strength training, high-intensity workouts, anabolic window nutrition
• Ovulatory phase: PRs, competitions, peak cognitive performance
• Luteal phase: reduced output, magnesium, complex carbs for mood

🏃 WORKOUT SYNC BY PHASE
• Exercise recommendations change every phase based on your hormone cycle
• Energy level tracking shows patterns across your cycle
• Periodization method used — not generic fitness advice
• Personalized by age group (20s, 30s, perimenopause)

📊 HORMONE WAVE VISUALIZATION
• See estrogen, progesterone, LH, and FSH across your full cycle
• Energy trend chart maps your logged energy against cycle phases
• Spot patterns — why you feel strong week 2, flat week 4
