Lunaire: Period, PCOS & Ovulation tracker.

Track your cycle, predict your period, understand your fertile window — all privately, on your device. No account. No cloud. No ads. Your data never leaves your phone.

🌙 PERIOD & CYCLE TRACKING
Log your period start and end, track flow intensity day by day, and build up a picture of your cycle over time. Lunaire Period, PCOS & Ovulation tracker learns from your real cycle data — not a generic 28-day assumption — so predictions get more accurate the longer you use it.

• Log period start, end and daily flow (light / medium / heavy / very heavy)
• Predicted period dates on the calendar based on your actual cycle history
• Cycle length trends and prediction confidence (Low → High)
• Period countdown ring on the home screen — always know how many days to go

🌸 PCOS & OVULATION
