# GyroSphere Trials vs Stack

The clearest difference is update cadence: Stack at every 10 days against GyroSphere Trials's every 2 months. Stack also leads on ratings volume (59K vs 1K) and rating (4.4 vs 4.2). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. GyroSphere Trials sells 10 one-off in-app purchases and Stack sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Stack holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Stack has 59K ratings behind it against 1K, so its average is the more settled of the two. Written reviews complicate that: 59% of GyroSphere Trials's written reviews are positive against 53% of Stack's, so the app with the better star average is not the one people write more warmly about.

GyroSphere Trials ships an update every 2 months, Stack every 10 days. The most recent releases landed on September 13, 2026 and September 24, 2026 respectively.
