About this app
Luma is a private cycle, period, and ovulation tracker designed to help you understand your body without sending your logs to a third-party server. Track your period, symptoms, mood, energy, sleep, stress, intimacy, discharge, basal body temperature, and water intake in a calm daily check-in. Luma turns your entries into clear cycle insights, including predicted period dates, fertile window, ovulation day, cycle history, mood patterns, and wellness trends. Plan ahead with: - Period, fertile window, and ovulation predictions - A cycle calendar with upcoming dates - Daily logs for flow, mood, symptoms, BBT, sleep, stress, and notes - Pattern insights across past cycles - Optional daily log, period supply, and contraceptive reminders - Optional Apple Health sync for cycle data and sleep import - Optional iCloud sync across your Apple devices - Home Screen and Lock Screen widgets Luma is built for privacy-first cycle awareness. Your data stays on your device unless you choose to enable iCloud or Apple Health sync. Medical disclaimer: Luma does not provide medical advice, diagnosis, treatment, or contraception. Predictions are informational only. Always consult a qualified healthcare professional for medical questions.
