Supplement Framework

The app uses a tiered supplement system aligned to your cycle phase:

Tier 1 (Foundation): Omega-3, Vitamin D3+K2, Magnesium, Methylated B-Complex
Tier 2 (Targeted): Ubiquinol, NAC, Curcumin, Prebiotics, Iron, Zinc
Tier 3 (Advanced): Creatine, Lithium Orotate, Methylene Blue

Data Storage

All data stays on your machine — no cloud required. Stored at ~/.fertility_tracker_data/fertility_tracker.json

Cycle Calculation

Ovulation is predicted using the luteal phase constancy method: the luteal phase (post-ovulation) is typically 14 days. Ovulation day = Cycle length − 14. The fertile window = 5 days before ovulation through 1 day after.

This method becomes more accurate as more cycle data is logged over time.

Astrology Features
