# Exoplanet vs Astronomy Game

The clearest difference is update cadence: Exoplanet at every 2 weeks against Astronomy Game's every 13 months. Exoplanet also leads on ratings volume (979 vs 10) and rating (4.7 vs 4.4). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Exoplanet sells 7 one-off in-app purchases and Astronomy Game sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Exoplanet holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Exoplanet has 979 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 91% of Exoplanet's written reviews are positive against 86% of Astronomy Game's.

Exoplanet ships an update every 2 weeks, Astronomy Game every 13 months. The most recent releases landed on November 10, 2026 and November 7, 2026 respectively.
