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.
Orrery

See the solar system as it really is — right now. Orrery draws every planet, moon and comet exactly where it is today, turning and tilted as it really is, ray-traced live on your iPhone. Spin a world under your finger, run time forward or back by centuries, and watch the planets move. EXPLORE • The Sun, eight planets, their moons, the dwarf planets, Vesta and Halley's Comet — placed from NASA JPL's data • Real surfaces from spacecraft maps: MESSENGER, Viking, Cassini, New Horizons and more • Saturn's rings, Earth's clouds and city lights, eclipses and moon shadows • A living Sun, with sunspots, flares and eruptions that follow the real solar cycle • Halley's Comet, tumbling as it really does, growing its coma and tails as it nears the Sun FLY THE MISSIONS Follow 18 spacecraft along their real paths — Voyager, Apollo 11, Artemis, Cassini, Juno, Perseverance, Parker Solar Probe, the James Webb Space Telescope and more — with the photographs they took. LOOK INSIDE Open up 16 worlds to see their cores, mantles and oceans, to scale. HEAR SPACE Real recordings from spacecraft: the Sun, Jupiter, Saturn, Earth's magnetic "chorus" and more. SKY ALERTS Eclipses, planets at their best, meteor showers and the view from Titan tonight — as gentle alerts, up to three a day and never at night, worked out on your iPhone. DARK SIDE A ship game among the worlds. Every world throws a long shadow away from the Sun, and a ship in one cannot be seen from afar, so hiding is the game: when a solar flare comes, get into a shadow. Five ships, three minutes, one life, against bots that fill the other seats. A training flight teaches the controls. It runs entirely on your iPhone, needs no account and sends nothing. Two ship colours come with Orrery Pro. YOUR BIRTHDAY SKY Tell Orrery the day you were born, once, and see your age on every planet, how far Earth has carried you round the Sun, and where the planets stood that day. Then travel to that day. The date stays on your iPhone. AND BEYOND • Earth's magnetic field, pressed by the solar wind • How the solar system travels through the galaxy, and the bubble that shields it • Stand on the Moon and Mars in 3D In English, Español, Português, Français, Русский, 中文 and O'zbekcha. ORRERY PRO Orrery is free to explore. The free plan shows a few ads, only at natural pauses after you finish something and never right after you open the app. A short video is optional and opens one locked item free for 30 minutes. Where the law asks, Orrery asks for your ad privacy choice before the first ad, and you can change it any time in Settings > Discover > Privacy choices. Orrery Pro takes every ad away and unlocks every mission, every interior, every sound, the 3D surfaces, the galaxy view, Earth's magnetic field, Ultra graphics and two Dark Side ship colours: yearly with a one-week free trial, monthly, or once for life. Payment is charged to your Apple Account at confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel them in your App Store account settings.

Verdict
The clearest difference is ads: RealTime Space at none against Orrery's shown. Orrery's advantage is iOS requirement (15.0 vs 26.0). On price, update cadence, in-app purchases and device support there is nothing between them.
