Verdict

The call

The clearest difference is rating: Forest Island at 4.8 against Stack Islands's 2.5. Forest Island also leads on update cadence (every 10 days vs every 2 months) and ratings volume (26K vs 2). Stack Islands's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Forest Island holds the better App Store score, 4.8 against 2.5. That said, the two scores are not equally well evidenced: Forest Island has 26K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 80% of Stack Islands's written reviews are positive against 79% of Forest Island's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Stack Islands ships an update every 2 months, Forest Island every 10 days. The most recent releases landed on October 5, 2026 and October 15, 2026 respectively.
