Fertility, BBT & cycle diary

Free · In‑App Purchases

Lunaire Cycle Tracker is a private, offline period and symptom diary for anyone managing PCOS (recently renamed PMOS) or tracking fertility. WHAT YOU CAN TRACK • Period dates, flow and spotting • Cycle lengths and history — your real pattern, cycle by cycle • Basal body temperature — with enough readings, the app learns your own luteal phase • Mood, anxiety, irritability and stress — across your whole cycle • Pain — cramps, pelvic pain, headaches, back pain • PCOS/PMOS symptoms — irregular cycles, acne, hair changes, energy • Sleep quality, insomnia and brain fog • 32 built-in symptoms in total • Food diary, cravings, exercise and supplements • Weight (kg, lbs or st), blood pressure and pulse • Appointments and daily notes (reminders with Premium) Every symptom and exercise is rated on a simple five-point scale — you can log the same symptom or exercise multiple times a day. PRIVACY-FIRST BY DESIGN • No accounts. No sign-up. Open the app and start logging. • No tracking. Your data lives in a local database only you control. • No ads. Ever. No analytics. • Works fully offline. PDF REPORTS (PREMIUM) Generate a clean PDF of your cycle history and symptom patterns — share it with your doctor or gynecologist in one tap. BUILT FOR REAL CYCLES Predictions come from your own logged cycles, not an "average" cycle, and with enough temperature readings the app uses your own luteal phase. Built for regular and irregular cycles, PCOS/PMOS, and anyone trying to conceive. FREE • Period, symptom, pain, food, exercise and supplement logging • Up to three entries per symptom per day • Cycle history and BBT • Calendar view, with your next period predicted • Weight, temperature and blood pressure • Appointments • One week of trends and charts • Your complete history, always browsable • Backup and restore to a file you keep • Light, dark and AMOLED themes, and a language picker PREMIUM • Fertile window and ovulation markers on the calendar and home ring • Trends over one month, three months, a year or all time • PDF reports • CSV data export • Twelve entries per symptom / exercise per day • Your own custom symptoms and exercises • Supplement and appointment reminders • A personalized home screen • Your top eight symptoms instead of three Period and fertility predictions are estimates, not guarantees, and should not be used as a method of contraception. These screenshots are just a small selection from the app. All screenshots show example data, not real records. Premium: an affordable monthly or yearly subscription, or a one-time lifetime purchase.
