# Spaceflight Simulator vs Solar Smash 2D

The clearest difference is ads: Spaceflight Simulator at none against Solar Smash 2D's shown. Spaceflight Simulator also leads on update cadence (every 9 days vs every 2 months) and ratings volume (98K vs 14K). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Spaceflight Simulator sells 10 one-off in-app purchases and Solar Smash 2D sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Spaceflight Simulator against 4.7 for Solar Smash 2D. That said, the two scores are not equally well evidenced: Spaceflight Simulator has 98K ratings behind it against 14K, so its average is the more settled of the two. Written reviews are what separate them: 85% of Spaceflight Simulator's written reviews are positive against 82% of Solar Smash 2D's.

Spaceflight Simulator ships an update every 9 days, Solar Smash 2D every 2 months. Both last shipped on October 27, 2026.
