Set against a haunting, atmospheric soundscape, the app shows planets and satellites in their correct positions, and offers mini movies, facts and other related tidbits.” - TNW “This jaw-dropping app provides a wholly interactive 3D model of our solar system, one that’s had me hooked for days. It’s the kind of thing you can imagine a science teacher using in the classroom of the future — except that we don’t have to wait.” - CNet “Zoom from Mercury to Pluto (which makes the cut in this app), passing each planet’s moons along the way. Because Solar Walk knows what time it is, the planets are in proper orientation to the Sun: Earth is dark where it is currently night and gradually lightens to daytime on the other side.” - NY Times "It's great for showing my students the relative positions of the planets in the solar system, the satellites orbiting the Earth and our place in the galaxy. Awesome with a smartboard as well." - by jbrown61 Solar Walk enables you to: ► Observe the 3D model of our Solar system with all its objects in real time and in a proper orientation. Turn into an astronomer and explore planets, moons, satellites, asteroids, dwarf planets, comets, stars and other celestial bodies. Enjoy gorgeous graphics and visuals while navigating through the solar system. ► Make virtual flights from one space object to another. ► Travel in time and see what the universe and our Solar system looked like at a certain period. ► Find an exciting view of the Milky Way Galaxy. ► Watch a collection of educational solar system movies to learn about space-related topics including Earth's moon phases, Earth's cycles, tidal phenomena, and zodiacal constellations. ► Enjoy 3D planetarium with the help of special glasses and activating the anaglyph mode. ► Share interesting screenshots of the app with your friends. ► Choose the view mode comfortable for you (orrery/true-to-scale).

Verdict
The clearest difference is price: Solar System Scope at Free against Solar Walk's $4.99. Solar System Scope also leads on iOS requirement (13.0 vs 15.0). Solar Walk's advantage is rating (4.7 vs 4.4) and ratings volume (8.1K vs 882). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Solar System Scope is free to download; Solar Walk costs $4.99 up front. Solar Walk sells 11 one-off in-app purchases and Solar System Scope sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Solar Walk holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Solar Walk has 8.1K ratings behind it against 882, so its average is the more settled of the two. Written reviews complicate that: 72% of Solar Walk's written reviews are positive against 76% of Solar System Scope's, so the app with the better star average is not the one people write more warmly about.
Solar Walk ships an update every 5 months, Solar System Scope every 4 months. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
