Verdict
The clearest difference is rating: Rocket Simulator at 3.8 against HM's 2.7. Rocket Simulator also leads on ratings volume (422 vs 6). 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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 2.7. That said, the two scores are not equally well evidenced: Rocket Simulator has 422 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 14% of HM's written reviews are positive against 10% 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 2, 2026 and October 19, 2026 respectively.
