Our fans say it even better: Wipe that look off your face by Nordicblood "Hey, you! Yes. You. The one staring at these words with that weird look of confusion and amusement. Stop. You look stupid. This game starts easy, and you'll think you have it in the bag, then whammy, you're ported to a world of hair-tearing frustration. Stop. Wipe that arrogant look of confidence off your face. You wit succeed. No one escapes the Gyrosphere. No one. I mean, if you feel like you can get over the difficult controls and fling your ball over the abyss below and land on a little platform with a little circular target on it that, depending on your speed and trajectory, will launch you to another platform of equally frustrating obstacles. See. That's the face I'm looking for, curious and determined. Give it a go, you may like it. I do. I haven't yet reached the end of all of the paths. I've sacrificed life and limb for the 'sphere. Welcome to it kid." Please contact us with feedback at WeListen@pronetis.com. We’d love to hear from you.

Verdict
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.
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. 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.
