Luma: Period & Cycle Tracker

Luma is a private period, cycle, and ovulation tracker that helps you understand your body—without sending your logs to a third-party server.

Track your menstrual cycle with a calm daily check-in for period flow, symptoms, mood, energy, sleep, stress, intimacy, discharge, basal body temperature (BBT), and water intake. Luma turns your entries into clear insights: predicted period dates, fertile window, ovulation day, cycle history, mood patterns, and wellness trends.

Plan ahead with:
• Period, fertile window, and ovulation predictions
• An easy-to-read cycle calendar with upcoming dates
• Daily logs for flow, mood, symptoms, BBT, sleep, stress, and notes
• Pattern insights across past cycles
• Optional reminders for daily logs, period supplies, and contraception
• Optional Apple Health sync for cycle data and sleep import
• Optional iCloud sync across your Apple devices
• Home Screen and Lock Screen widgets
• Optional read-only calendar sharing with a partner

Built for privacy-first cycle awareness. Your data stays on your device unless you choose iCloud or Apple Health sync.
