Your body, your data.
A private period tracker with cycle predictions, symptom logging and statistics. Your records stay on your device.
Your cycle, symptom, mood, flow, note and pregnancy records are kept on your device only. They are not uploaded to our servers or to any cloud service. No account is required.
See your next period predicted from your own logged history. Predictions appear once you have recorded two or more cycles.
Record your mood, flow level, symptoms (such as cramps, headache, fatigue, bloating and pill taken) and a short note for each day.
A calendar view with color-coded cycle phases and a cycle dial on the home screen.
Review your cycle statistics and trends.
An optional daily reminder, scheduled on your device, to log your day. You choose the time.
If you may be pregnant, enter your last period start date to see the pregnancy week and an estimated due date. This data also stays on your device.
Export your cycle and symptom records as a CSV file to bring to a doctor's appointment. You choose where the file goes.
Available in 39 languages.
Core tracking is free: recording periods, symptoms, moods and flow, cycle predictions, the calendar, statistics, the daily reminder, pregnancy mode and data export. The App shows ads to users who have not purchased Premium.
Premium adds a passcode lock (protect the App with Face ID or your device passcode), shows your estimated ovulation day and fertile window on the home screen, and removes ads.
Premium is offered as an auto-renewing subscription and may also be offered as a one-time purchase. Plans, prices, and any free trial offer (including a 7-day free trial for eligible new subscribers) are those shown in the App Store at the time of purchase.
Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel your subscription in your Apple ID Account Settings.
Requires iOS 18.0 or later. Your records are stored on your device. No sign-up is required.
Note: LunaCycle is a personal tracking tool, not a medical device. Cycle, ovulation, fertile-window and pregnancy-week estimates are rough guides based on the dates you enter and are not guaranteed. Do not use the App for contraception (birth control), to diagnose any condition, or as a substitute for professional care. If you have health concerns, an irregular or unusual cycle, severe pain or a possible pregnancy, consult a doctor.
