# A Solar System Journey vs ARPlanets 2

The clearest difference is rating: A Solar System Journey at 4.5 against ARPlanets 2's 3.3. A Solar System Journey also leads on in-app purchases (none vs 1) and ratings volume (434 vs 15). ARPlanets 2's advantage is ads (none vs shown) and review sentiment (57% vs 26%). On price and device support there is nothing between them.

Both are free to download. ARPlanets 2 sells 1 one-off in-app purchase. A Solar System Journey asks for nothing beyond the download.

A Solar System Journey holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: A Solar System Journey has 434 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 26% of A Solar System Journey'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.

A Solar System Journey ships an update every 6 months, ARPlanets 2 every 6 weeks. The most recent releases landed on October 21, 2026 and October 26, 2026 respectively.
