No spaceship needed. Drift through the solar system with a fingertip, approach real planets, scan and log your discoveries — a calm, immersive space journey. 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 ■ Subscription Cosmic Pass is an auto-renewable subscription (monthly or yearly plan, with a 1-week free trial). It renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period. You can manage or cancel anytime in Settings → Apple ID → Subscriptions.
