# Planet Gravity vs Rocket Simulator

The clearest difference is review sentiment: Planet Gravity at 44% against Rocket Simulator's 11%. Planet Gravity also leads on rating (4.2 vs 3.8). Rocket Simulator's advantage is update cadence (every 2 months vs every 6 months) and monetization model (free with in-app purchases vs paid). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Planet Gravity sells 1 one-off in-app purchase and Rocket Simulator sells 6 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Planet Gravity holds the better App Store score, 4.2 against 3.8. That said, the two scores are not equally well evidenced: Rocket Simulator has 428 ratings behind it against 54, so its average is the more settled of the two. Written reviews point the same way: 44% of Planet Gravity's written reviews are positive against 11% of Rocket Simulator's.

Planet Gravity ships an update every 6 months, Rocket Simulator every 2 months. Both last shipped on November 3, 2026.
