Verdict
The clearest difference is price: Space Expansion at Free against PlanetBuilder's $0.99. Space Expansion also leads on update cadence (every 10 days vs every 26 months) and ratings volume (21 vs 7). PlanetBuilder's advantage is ads (none vs shown) and review sentiment (71% vs 60%). On rating, in-app purchases, device support and iOS requirement there is nothing between them.

Space Expansion is free to download; PlanetBuilder costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Space Expansion holds the better App Store score, 4.3 against 4.1. Both are backed by a comparable volume of ratings — 7 and 21 respectively. Written reviews complicate that: 71% of PlanetBuilder's written reviews are positive against 60% of Space Expansion's, so the app with the better star average is not the one people write more warmly about.
PlanetBuilder ships an update every 26 months, Space Expansion every 10 days. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
