## What is CosmicObserver?

CosmicObserver lets you travel real planets — of our solar system and beyond — from an observer's first-person view.

You don't pilot a ship; you drift through space with your gaze and fingertips.
Lock onto stars and planets, approach, scan, and record what you observe — space as a journey, not a catalog.

■ Features
・Real astronomical bodies based on public data (NASA Exoplanet Archive and more)
・FPS view with a virtual stick for free drifting
・Scientific honesty: observed / estimated / artistic values marked by color and label
・A "Cosmic Passport" and discovery collection
・A daily destination to gently explore the cosmos

■ Cosmic Pass (one-time purchase)
The solar system is free. Cosmic Pass — a single one-time purchase — unlocks all star systems, exoplanets, unlimited dailies, and the frontier beyond.

Note: Exoplanet surfaces are estimations/artistic renderings, not photographs. This app is not endorsed by NASA.

■ In-App Purchase
Cosmic Pass is a one-time purchase. There is no subscription, nothing renews, and there is nothing to cancel. After a new device or a reinstall, use "Restore purchases" on the Cosmic Pass screen or in Settings with the same Apple Account. Family Sharing is supported.
