Lunawise

Tiny app, zero tracking, no subscription. All moon data calculated offline on your device. Buy once, own forever. Your data stays yours.

Lunawise shows you exactly what the Moon looks like right now — and what it will look like tomorrow, next week, or any day of the month.

Open the app and you'll see a beautifully rendered Moon that matches the real sky at this very moment. The illuminated fraction updates in real time, so the visualization always reflects what's happening above you. Below the Moon you'll find the current illumination percentage and the age of the current cycle — everything you need at a single glance.

Planning ahead? The built-in 30-day calendar lets you browse any month and tap any date to see phase details instantly. Navigate forward or backward to explore past and future cycles with ease.

If you want to know when the Moon rises and sets at your location, just enable location access once. Lunawise calculates those times locally on your device — no server, no internet connection required. Your data never leaves your phone.

Widgets bring the Moon to your Home Screen and Lock Screen. Choose from three visual styles — realistic, minimal, or illustrated — and pick the size that fits your setup. Small, medium, and large widgets are available for your Home Screen, plus circular, rectangular, and inline options for your Lock Screen.

On Apple Watch, a dedicated app and complications keep the current phase on your wrist. Glance at your watch face and know instantly whether tonight's sky will be bright or dark.

Never miss a special night: turn on reminders for upcoming events and receive a notification on the morning of the day — giving you time to plan your evening.

Lunawise works entirely offline. Every calculation runs on your device using proven astronomical formulas. No subscription, no ads, no account required. Buy once, use forever — across iPhone, iPad, and Apple Watch.

Available in 11 languages: English, German, French, Italian, Japanese, Korean, Brazilian Portuguese, European Portuguese, Spanish, Mexican Spanish, and Simplified Chinese.
