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.

Verdict

The call

The clearest difference is price: GalacticAR at Free against Solar Walk's $4.99. GalacticAR also leads on update cadence (every 4 weeks vs every 5 months) and review sentiment (88% vs 72%). Solar Walk's advantage is ratings volume (8.1K vs 116) and rating (4.7 vs 4.5). On ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Solar Walk holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Solar Walk has 8.1K ratings behind it against 116, so its average is the more settled of the two. Written reviews complicate that: 72% of Solar Walk's written reviews are positive against 88% of GalacticAR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Solar Walk ships an update every 5 months, GalacticAR every 4 weeks. The most recent releases landed on September 24, 2026 and September 19, 2026 respectively.
