Lune: Period & Cycle Tracker

Lune is a private period tracker and ovulation calendar. Log your period, symptoms and mood in seconds and always know where you are in your cycle.
No account, no ads, no tracking. Your cycle data stays on your iPhone.
See when your next period is due, your fertile window and estimated ovulation, and get a reminder 2 days before.

YOUR CYCLE AT A GLANCE
One ring shows today, your period days and your fertile window. See how many days are left until your next period, your cycle day and your current phase (period, follicular, fertile, luteal) with a short, practical tip for each.

LOG IN SECONDS
Flow, cramps, headache, bloating, acne, fatigue, tender breasts and mood. Tap, save, done. Logged days are marked on the calendar.

PERIOD CALENDAR
Past periods, predicted periods, fertile days and estimated ovulation, month by month.

PERIOD PREDICTIONS
Set your usual cycle and period length once, or simply use the averages. Tap "Period started" when it begins and Lune updates your next period, fertile window and estimated ovulation.

CYCLE INSIGHTS
Your average cycle length, average period length and a chart of your last 6 cycles, so you can see how regular your cycle is.

GENTLE REMINDERS
A heads-up 2 days before your period is due.

PRIVATE BY DESIGN
No sign-up, nothing sent to our servers. Lock Lune with Face ID, export your data or delete it anytime.
