Verdict
The clearest difference is rating: 3D Solar System at 4.4 against ARPlanets 2's 3.3. 3D Solar System also leads on ratings volume (1.7K vs 15) and update cadence (fortnightly vs every 6 weeks). ARPlanets 2's advantage is ads (none vs shown) and review sentiment (57% vs 29%). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. 3D Solar System sells 12 in-app purchases, starting at $7.99 per 7 days and ARPlanets 2 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
3D Solar System holds the better App Store score, 4.4 against 3.3. That said, the two scores are not equally well evidenced: 3D Solar System has 1.7K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 29% of 3D 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.
3D Solar System ships an update fortnightly, ARPlanets 2 every 6 weeks. The most recent releases landed on September 22, 2026 and August 27, 2026 respectively.
