Lunavia: Period Tracker

Your cycle, predictions and symptoms in one calm app — kept on your iPhone. No account, no ads, no tracking. Works with Apple Health.

Understand your cycle and keep it yours. Lunavia predicts your next period and fertile window, helps you log symptoms in seconds and keeps everything on your iPhone — no account, no ads, no tracking.

Your health data stays on your device. There is no Lunavia server and no cloud copy of your entries. Apple Health is optional, and you choose exactly what is shared.

TRACK IN SECONDS • Log period start and end, flow, spotting, symptoms, mood and notes • Quick Log from the Today screen, widgets, Siri, Shortcuts or Control Center • Edit any past day in the calendar • Daily log and pill reminders, plus a gentle heads-up before your period

PREDICTIONS YOU CAN READ • Next period and estimated fertile window, shown as a range rather than a single day • Predictions adapt to irregular cycles and show how confident they are • Optional basal body temperature, Apple Watch wrist temperature and LH test entries help confirm ovulation after it happens • Modes for general tracking, trying to conceive, perimenopause and hormonal contraception (reminders instead of predictions)

LEARN FROM SOURCES • Short articles on every cycle phase, PMS, period pain, heavy periods and more • Every paragraph links to the public health source it is based on • A clear "when to see a doctor" section

PRIVATE BY DESIGN • Face ID, Touch ID or passcode lock, with the app hidden in the app switcher • Private mode uses neutral wording in notifications and widgets • Export your data (optionally password-encrypted) or delete everything at any time • No analytics, no advertising, no tracking

APPLE HEALTH AND WIDGETS • Two-way sync of menstrual data with Apple Health, only for the types you allow • Predictions are never written to Apple Health • A Home Screen and a Lock Screen widget are included for free

LUNAVIA PRO (OPTIONAL SUBSCRIPTION) Everything above is free. Lunavia Pro adds: • Smart summaries: a plain-language overview of your recent cycles and why one may have differed. On iOS 26 or later with Apple Intelligence they are written by Apple's on-device model; on other devices you get rule-based summaries. Nothing is sent to the cloud. • A doctor-ready PDF summary of your recent cycles (exporting your raw data stays free) • Every widget size, including the interactive Quick Log widget and more Lock Screen styles

Lunavia Pro is available as a monthly or yearly auto-renewing subscription; the yearly plan includes a 7-day free trial for eligible users. The price for your region is shown in the app before you subscribe. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. You can manage or cancel it in your Apple Account settings. Family Sharing is supported.

Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: available in the app under Settings → Privacy & lock and on our website.

IMPORTANT Lunavia is not a medical device and does not diagnose any condition. Predictions are estimates and must not be used as contraception or to prevent pregnancy. Talk to a doctor or other health professional about your health.

Requires iOS 18 or later on iPhone. Smart summaries written by Apple Intelligence require iOS 26 or later and a device that supports Apple Intelligence.
