# Solar System by Clementoni vs Solar Explorer 3D

The clearest difference is review sentiment: Solar System by Clementoni at 100% against Solar Explorer 3D's 50%. Solar System by Clementoni also leads on monetization model (free vs free with in-app purchases) and iOS requirement (11.0 vs 16.0). Solar Explorer 3D's advantage is rating (4.2 vs 3.6) and update cadence (every 2 weeks vs every 24 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Solar System by Clementoni sells 1 one-off in-app purchase and Solar Explorer 3D sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Solar Explorer 3D holds the better App Store score, 4.2 against 3.6. That said, the two scores are not equally well evidenced: Solar Explorer 3D has 25 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Solar System by Clementoni's written reviews are positive against 50% of Solar Explorer 3D's, so the app with the better star average is not the one people write more warmly about.

Solar System by Clementoni ships an update every 24 months, Solar Explorer 3D every 2 weeks. Both last shipped on October 24, 2026.
