Lunara – Period Tracker

Your cycle, your data — on your iPhone only. No account, no cloud, no subscription: predictions and insights are computed privately on-device. Pay once, yours forever.

Lunara keeps your most personal health data exactly where it belongs — on your iPhone. No account, no cloud, no subscription.

TRACK YOUR CYCLE, PRIVATELY Log your period, flow, symptoms, and mood in seconds. Lunara builds a picture of your unique cycle entirely on-device, never sending a byte to any server.

BEAUTIFUL CYCLE WHEEL Your home screen shows exactly where you are in your cycle today — menstrual, follicular, ovulatory, or luteal — with a live-colored ring that changes with each phase.

PREDICTIONS YOU CAN TRUST Unlock next-period and fertile-window estimates powered by your own history. Lunara learns from your cycles and shows confidence based on your consistency — not an algorithm built on strangers' data.

LOG IN SECONDS Tap flow level, pick symptoms from curated favorites, done. Backfill any past day from the calendar without losing your history.

HOME SCREEN WIDGET See your cycle day and days-to-period at a glance — right from your home screen.

INSIGHTS & HISTORY Cycle-length chart, average, range, and streak — all calculated locally. Export as CSV anytime.

BUILT FOR PRIVACY • All data stays on this iPhone • Optional Face ID lock • No account or email needed • No tracking, no ads, no subscription

PAY ONCE, YOURS FOREVER Unlock predictions, insights, and export with a single $5.99 purchase. No recurring charges, ever.

Lunara is a wellness companion. Estimates are based on your personal history and are not a substitute for medical advice or birth control.
