Moon Rotor

Turn the moon through time. Keep a date that matters, share its moon, and bring a quiet moon-and-ring widget to your Home Screen.

Turn the moon through time.

Trace around the moon and feel each day click beneath your finger. Give it a flick and let it coast. Tap the moon to return to today. Moon Rotor makes the lunar cycle something you can explore by touch, with more to discover when you tap the lunar readout.

Keep a date that matters Save a birthday, an anniversary, or a night you want to remember in Moon Keepsakes. Add your own title and note, then create a card showing that date's moon in Gold, Midnight, or Paper. Notes are left out of shared cards unless you choose to include an excerpt in the preview.

A little moon, always nearby Add a textured moon and subtle ring to your Home Screen. Tap the widget to open the rotor. Lock Screen widgets put lunar details within a glance.

Look a little deeper Explore phase, illumination, lunar age, and upcoming full and new moons. Choose a date in Moon Calendar. See the Moon estimates moonrise, moonset, height, and direction for a city or coordinates you choose, using calculations on your device without requesting location access.

Make room for your own rhythm Choose local reminder times and an optional notice the day before a full or new moon. Turn on Astronomy Only for lunar facts, or explore optional reflective zodiac symbolism and Tonight guidance. On supported iPhones, optional on-device tailoring has a curated offline fallback.

Private by design No account, ads, analytics, tracking, subscriptions, or developer-operated cloud service. Preferences, keepsakes, observing locations, and saved reflections are stored on your device. You choose whether to share a keepsake card.

Lunar astronomy covers 2000 through 2050. Local sky estimates assume a clear, level horizon; terrain, weather, and polar conditions affect what you can see. Zodiac and Tonight content are reflection, not scientific claims or professional advice. Moon Rotor does not predict personal outcomes.
