Luna Cycle: Your Period Diary

Private period & cycle journal

Free · Designed for iPad. Not verified for macOS.

Add previous period dates and learn your own rhythm over time. Free, ad-free cycle tracking with records stored on your device. Your cycle is yours. Luna Cycle helps you record periods and daily observations in a calm, simple calendar. • Add, edit, or delete historical period start dates and known end dates. • Log flow, symptoms, energy, mood, and personal notes. • Learn your own rhythm: Luna does not assign everyone a 28- or 30-day cycle. After at least three completed cycle intervals, it may show broad estimated period-start ranges based on your records. It does not produce a personal date after only one or two cycles. • Review your records in the calendar and insights. Schedule local reminders on supported devices. • Export or import JSON backups and clear local data in Settings. All current features are free in this release. There are no ads, premium tier, subscriptions, or in-app purchases. No Luna account is required; core health records are stored on your device and are not uploaded to a Luna server. Interface languages: Turkish, English, Russian, German, and Spanish. Important: Luna Cycle is not a medical device and does not provide diagnosis, treatment, or medical advice. Estimates are approximate and informational. It does not calculate ovulation timing or identify fertile or safe days. Unmarked calendar days must not be treated as safe from pregnancy. Do not use the app for contraception or pregnancy planning. Consult a qualified healthcare professional about health concerns and local emergency services in an emergency. Support: info@ewocom.com
