Verdict
The clearest difference is ads: Slime at none against Super Starfish's shown. Slime also leads on update cadence (every 5 days vs every 3 weeks) and iOS requirement (9.0 vs 15.0). Super Starfish's advantage is ratings volume (30K vs 348) and rating (4.8 vs 4.5). On price, review sentiment, in-app purchases and monetization model 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. Super Starfish sells 16 one-off in-app purchases and Slime sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Super Starfish holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Super Starfish has 30K ratings behind it against 348, so its average is the more settled of the two. Written reviews point the same way: 87% of Super Starfish's written reviews are positive against 85% of Slime's.
Super Starfish ships an update every 3 weeks, Slime every 5 days. The most recent releases landed on October 21, 2026 and October 16, 2026 respectively.
