PocketCosmos vs RealTime Space

PocketCosmos employs a real-time gravitational computation engine, accurately simulating celestial motion in a SceneKit 3D environment. Technical Specifications: - Gravity formula: F = G x M x m / r2, real-time N-body simulation - Rendering: SceneKit + Metal, smooth 60fps performance - Scenarios: 8 curated astronomical simulations - Data source: Parameterized from NASA/JPL public datasets 8 Simulation Scenarios: 1. Solar System Panorama - all planets in proportional orbits 2. Inner Planets - close observation of Mercury through Mars 3. Outer Planets - Jupiter to Pluto orbital dynamics 4. Asteroid Belt - dozens of asteroid distribution simulation 5. Jupiter System - Galilean moon orbital mechanics 6. Pluto System - elliptical orbit and Charon tidal locking 7. Gravity Slingshot - probe acceleration effect demonstration 8. Solar System Top View - global perspective planetary alignment Education Module (6 topics): - Law of Universal Gravitation - Kepler's Three Laws - elliptical orbits, area law, period law - Tidal Locking - synchronous rotation mechanism - Roche Limit - critical disintegration distance - Supernova - stellar evolution final stage - Lagrange Points - three-body gravitational equilibrium Requirements: iOS 17.0+ | iPhone only Privacy: Zero data collection, fully local execution

Strap in. RealTime Space puts you at the helm of your own starship in a photoreal, full-scale universe — every planet, every major moon, and 8,920 real stars, all in the palm of your hand. FLY ANYWHERE Real navigation physics with thrust, drift and 100x warp. Skim Jupiter's storms, cruise through Saturn's sunlit rings, chase comets across the system, or point the nose at a star and just go. A REAL SKY Every star you see is real — 8,920 naked-eye stars with their true names, brightness and 3D positions, plus the Milky Way band exactly where it belongs. Fly to Sirius, Betelgeuse or Vega and watch a point of light resolve into a blazing sun. THE WHOLE SOLAR SYSTEM All eight planets in photoreal detail, the Moon, volcanic Io, icy Europa, hazy Titan, Enceladus and its geysers, the asteroid belt, famous comets, deep-space nebulae — and Sagittarius A*, the black hole at the center of the galaxy. THREE WAYS TO FLY VISOR — a clean, unobstructed view of space. HELM — a full cockpit around you. CHASE — follow your own ship from behind. SCAN AND DISCOVER Scan planets, moons and stars to fill your Field Guide, track your journey on the Space Map, and complete missions as you explore. MADE TO FEEL REAL Analytic eclipse and ring shadows, real star colors, a procedural engine soundscape, and a sky accurate enough to learn constellations from. FREE FOR 60 DAYS Everything is free for your first 60 days. Keep the whole universe forever with a single $1.99 unlock — no subscription, no ads, no account, no data collection. WORKS WITH VOICEOVER Every control is labeled — thrust, warp, the joystick, the camera views and the fly-to list — so the ship can be flown with a screen reader turned on.
