# Solar System Scope vs Star Walk 2 Plus

The clearest difference is ads: Solar System Scope at none against Star Walk 2 Plus's shown. Solar System Scope also leads on iOS requirement (13.0 vs 15.0). Star Walk 2 Plus's advantage is ratings volume (95K vs 882) and update cadence (every 6 weeks vs every 4 months). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Solar System Scope sells 1 one-off in-app purchase and Star Walk 2 Plus sells 12 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Star Walk 2 Plus holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Star Walk 2 Plus has 95K ratings behind it against 882, so its average is the more settled of the two. Written reviews complicate that: 76% of Solar System Scope's written reviews are positive against 70% of Star Walk 2 Plus's, so the app with the better star average is not the one people write more warmly about.

Solar System Scope ships an update every 4 months, Star Walk 2 Plus every 6 weeks. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
