# Kids Solar System vs Solar System Planets

The clearest difference is rating: Solar System Planets at 3.3 against Kids Solar System's 2.8. Kids Solar System's advantage is update cadence (monthly vs every 3 months) and iOS requirement (11.0 vs 15.0). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Kids Solar System sells 1 one-off in-app purchase and Solar System Planets sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Solar System Planets holds the better App Store score, 3.3 against 2.8. Both are backed by a comparable volume of ratings — 8 and 10 respectively. Written reviews complicate that: 7% of Kids Solar System's written reviews are positive against 0% of Solar System Planets's, so the app with the better star average is not the one people write more warmly about.

Kids Solar System ships an update monthly, Solar System Planets every 3 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
