Both are free to download. Solar System by Clementoni sells 1 one-off in-app purchase and GPT Solar System Explorer sells 5 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
GPT Solar System Explorer holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: GPT Solar System Explorer has 96 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 0% of GPT Solar System Explorer'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, GPT Solar System Explorer every 2 weeks. The most recent releases landed on November 5, 2026 and November 4, 2026 respectively.
