# Solar Walk vs Solar System Scope

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.

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 27, 2026 and September 25, 2026 respectively.
