Verdict

The call

The clearest difference is review sentiment: Stack Islands at 80% against Fly Challenge's 27%. Stack Islands also leads on ads (none vs shown) and update cadence (every 2 months vs every 5 months). Fly Challenge's advantage is rating (4.2 vs 2.5) and ratings volume (1.3K vs 2). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Stack Islands sells 1 one-off in-app purchase and Fly Challenge sells 20 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Fly Challenge holds the better App Store score, 4.2 against 2.5. That said, the two scores are not equally well evidenced: Fly Challenge has 1.3K 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 27% of Fly Challenge'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, Fly Challenge every 5 months. The most recent releases landed on October 5, 2026 and October 13, 2026 respectively.
