Private by design

Wonder doesn’t need Wi-Fi.

Astronomy works offline. Your reflections stay on your device. Optional on-device intelligence on supported iPhones has a curated offline fallback.

Grounded in astronomy

Science stays factual.
Reflection stays reflective.

Lunar calculations are validated from 2000 through 2050. Reflective zodiac content is always separate from the astronomy.

Accuracy & limitations

The Moon is waiting.

Find your own phase.

A little curiosity. A little calm. A whole new orbit.
