How Dawn Phase handles PCOS differently
No 28-day assumption
Standard apps predict your next period by adding your average cycle length to your last period date. With PCOS, cycles range from 21 to 90+ days — or disappear entirely. Dawn Phase calculates from your actual last period start and doesn't alert you when you 'miss' a period.
Full-cycle symptom tracking
PCOS symptoms — acne, mood changes, bloating, fatigue, hair — don't cluster neatly around your period. Track them every day, mapped to your actual cycle day. After several months, patterns emerge even in irregular cycles.
Doctor-ready data export
Generate a PDF report of your symptom and cycle history in one tap. Export to CSV anytime. When you see your endocrinologist, arrive with data rather than trying to recall months of symptoms from memory.
Common questions
Does it work with very irregular cycles?
Yes. Dawn Phase supports cycles from 21 to 90+ days. It doesn't break or produce misleading alerts when cycles are long or absent — it simply waits for your next logged period start and recalibrates. There are no 'late period' warnings based on a 28-day assumption.
Can I track PCOS symptoms, not just periods?
Yes. Log acne, bloating, fatigue, mood, energy, hair changes, and 40+ other symptoms every day. The insights view shows how your symptoms cluster across cycles, even when those cycles don't follow a regular pattern. You can export your full history as a CSV for endocrinologist visits.
How does it handle months with no period?
Dawn Phase doesn't pressure you to fit into a standard cycle model. If you go 60 or 90 days without a period, it records the current cycle day from your last logged period start and waits. When your next period starts, you log it and Dawn Phase recalibrates automatically. No errors, no broken predictions.
