Verdict

The call

The clearest difference is ads: Slime Pizza at none against High Octane!'s shown. Slime Pizza also leads on update cadence (every 2 weeks vs every 4 months) and ratings volume (240 vs 8). High Octane!'s advantage is rating (4.3 vs 3.9). On price, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

High Octane! holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Slime Pizza has 240 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 61% of Slime Pizza's written reviews are positive against 44% of High Octane!'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Slime Pizza ships an update every 2 weeks, High Octane! every 4 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
