About 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 ・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 affiliated with or 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.
