# Planet simulation vs Swoopy Space

The clearest difference is rating: Swoopy Space at 4.4 against Planet simulation's 3.9. Swoopy Space also leads on update cadence (fortnightly vs every 8 months). Planet simulation's advantage is in-app purchases (none vs 1) and ratings volume (165 vs 44). On price, review sentiment, ads and device support there is nothing between them.

Swoopy Space holds the better App Store score, 4.4 against 3.9. Both are backed by a comparable volume of ratings — 165 and 44 respectively. Written reviews complicate that: 74% of Planet simulation's written reviews are positive against 71% of Swoopy Space's, so the app with the better star average is not the one people write more warmly about.
