# Solar System vs ARPlanets 2

The clearest difference is rating: Solar System at 4.0 against ARPlanets 2's 3.3. Solar System also leads on iOS requirement (11.0 vs 17.0). ARPlanets 2's advantage is update cadence (every 6 weeks vs every 14 months) and review sentiment (57% vs 38%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Solar System sells 1 one-off in-app purchase and ARPlanets 2 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Solar System holds the better App Store score, 4.0 against 3.3. Both are backed by a comparable volume of ratings — 25 and 15 respectively. Written reviews complicate that: 38% of Solar System's written reviews are positive against 57% of ARPlanets 2's, so the app with the better star average is not the one people write more warmly about.

Solar System ships an update every 14 months, ARPlanets 2 every 6 weeks. The most recent releases landed on October 3, 2026 and September 27, 2026 respectively.
