# ST vs Fly Challenge

The clearest difference is rating: ST at 5.0 against Fly Challenge's 4.2. Fly Challenge's advantage is review sentiment (26% vs 0%) and ratings volume (1.3K vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ST 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.

ST holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Fly Challenge has 1.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of ST's written reviews are positive against 26% of Fly Challenge's, so the app with the better star average is not the one people write more warmly about.

ST ships an update every 3 months, Fly Challenge every 5 months. The most recent releases landed on October 17, 2026 and October 30, 2026 respectively.
