Verdict
The clearest difference is review sentiment: Idle Alien at 100% against Slime Weapon Master's 55%. Idle Alien also leads on in-app purchases (none vs 11) and update cadence (every 11 days vs every 2 months). Slime Weapon Master's advantage is rating (4.8 vs 4.5) and ratings volume (5.5K vs 123). On price, ads and device support there is nothing between them.

Both are free to download. Slime Weapon Master sells 11 one-off in-app purchases. Idle Alien asks for nothing beyond the download.
Slime Weapon Master holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Slime Weapon Master has 5.5K ratings behind it against 123, so its average is the more settled of the two. Written reviews complicate that: 100% of Idle Alien's written reviews are positive against 55% of Slime Weapon Master's, so the app with the better star average is not the one people write more warmly about.
Idle Alien ships an update every 11 days, Slime Weapon Master every 2 months. The most recent releases landed on July 4, 2026 and September 24, 2026 respectively.
