Verdict
The clearest difference is price: ARPlanets 2 at Free against Planetarium 3D's $1.99. ARPlanets 2 also leads on ratings volume (15 vs 1). Planetarium 3D's advantage is rating (5.0 vs 3.3) and in-app purchases (none vs 1). On review sentiment, update cadence, ads 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
ARPlanets 2 is free to download; Planetarium 3D costs $1.99 up front. ARPlanets 2 sells 1 one-off in-app purchase. Planetarium 3D asks for nothing beyond the download.
Planetarium 3D holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: ARPlanets 2 has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Planetarium 3D'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.
Both ship on a similar rhythm, roughly every 6 weeks. Both last shipped on October 29, 2026.
