Lumina:Period & Cycle

Know your cycle. Keep it yours. Lumina is a private period and cycle intelligence app built around one simple principle: your body’s data belongs to you. Everything you log stays on your device by default. No account, no ads, and no third-party tracking—just a calm, thoughtfully designed space to understand your cycle. TODAY, CLEARLY • See your cycle day, current phase, and what to expect in one calm view • Get phase-aware guidance for energy, meals, sleep, and movement • View next-period and estimated ovulation-window forecasts on a clear monthly calendar PREDICTIONS YOU CAN UNDERSTAND Most cycle apps give you a date. Lumina also shows you the context behind it. See whether a forecast is based mainly on calendar history or supported by recently logged signals, and learn what information could improve its confidence. FERTILITY SIGNALS, IN CONTEXT Log LH test results, basal body temperature (BBT), cervical mucus, and cycle symptoms. Lumina combines these signals with your cycle history to provide clearer context—not false certainty. TOOLS THAT FOLLOW YOUR PHASE • Quick Log: record flow, cramps, mood, LH, BBT, and notes in seconds • Movement: explore phase-aware session ideas • Nutrition: discover food ideas matched to your current phase • Reminders: receive gentle cycle and logging notifications at useful times SUPPORT FOR DIFFERENT LIFE STAGES Adjust Lumina for cycle tracking, trying to conceive, pregnancy, postpartum, or perimenopause.
