The universe, right in your pocket. "3D Solar System Tour" is an easy-to-use planetarium app that recreates the Solar System with beautiful 3D graphics, soothing BGM, and detailed voice narration. No complex controls required. Just relax and listen to the stories of the stars. 【Main Feature: Audio Guide Tour】 Narrated Solar System Tour The highlight of this app is the "Tour Mode," which automatically takes you on a journey through all the planets. Just like a museum guide, a calm voice explains the mysteries and characteristics of each planet. Perfect for relaxing before bed or learning something new during your commute. (Available via Rewarded Ads or Premium Plan) 【Other Features】 Beautiful 3D Simulation Explore the Sun, Mercury, Venus, Earth, Moon, Mars, Jupiter, Saturn, Uranus, and Neptune. Rotate planets with a swipe or zoom in to see their textures. Experience the Vastness: "Real Scale Mode" Switch to scientifically accurate size ratios and distances with a single tap. Note: In this mode, the Sun is massive, while other planets appear merely as tiny dots. While not visually detailed, this mode offers a powerful educational perspective on how vast and empty space truly is. Simple Warp Travel In "Exploration Mode," you can experience the atmosphere of traveling to planets aboard a spaceship. Note: This is a simple visual transition to jump to your destination, not a complex flight simulator. Interesting Astronomical Data Core Data: Diameter, Mass, Orbital/Rotational periods. Travel Time: See how long it would take to reach each planet using the "Apollo" spacecraft or the modern "Parker Solar Probe." 【Premium Features】 The app is free to download. Upgrading to the Premium Plan unlocks: ・Ad-Free Experience: Remove all ads. ・Unlimited Audio Tours: Access the full guided tour without watching reward ads.
