Verdict

The call

The clearest difference is in-app purchases: Muscle Boy at none against Gameworld Master's 10. Muscle Boy also leads on review sentiment (67% vs 44%). Gameworld Master's advantage is rating (4.7 vs 4.4) and update cadence (every 4 weeks vs every 3 months). On price, ads, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Gameworld Master holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 4.3K and 17K respectively. Written reviews complicate that: 67% of Muscle Boy's written reviews are positive against 44% of Gameworld Master's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Muscle Boy ships an update every 3 months, Gameworld Master every 4 weeks. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
