# Space Knowledge Quiz vs Galaxy Map

The clearest difference is ratings volume: Galaxy Map at 600 against Space Knowledge Quiz's 11. Galaxy Map also leads on update cadence (every 5 weeks vs every 4 months) and review sentiment (80% vs 67%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Space Knowledge Quiz sells 7 in-app purchases, starting at $1.99 per 7 days and Galaxy Map sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Space Knowledge Quiz against 4.6 for Galaxy Map. That said, the two scores are not equally well evidenced: Galaxy Map has 600 ratings behind it against 11, so its average is the more settled of the two. Written reviews are what separate them: 67% of Space Knowledge Quiz's written reviews are positive against 80% of Galaxy Map's.

Space Knowledge Quiz ships an update every 4 months, Galaxy Map every 5 weeks. The most recent releases landed on September 8, 2026 and September 24, 2026 respectively.
