Lumina:Period & Cycle

Your cycle, beautifully clear — and completely private. Honest forecasts, real fertility signals, and data that never leaves your iPhone. Free to track.

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.

One flexible experience that can change with you.
