# HM vs Rocket Simulator

The clearest difference is rating: Rocket Simulator at 3.8 against HM's 2.4. Rocket Simulator also leads on ratings volume (428 vs 7). HM's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. Rocket Simulator sells 6 in-app purchases, starting at $6.99 per 7 days. HM asks for nothing beyond the download.

Rocket Simulator holds the better App Store score, 3.8 against 2.4. That said, the two scores are not equally well evidenced: Rocket Simulator has 428 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 14% of HM's written reviews are positive against 11% of Rocket Simulator's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
