# GravityMan vs High Octane!

The clearest difference is rating: GravityMan at 4.6 against High Octane!'s 4.0. GravityMan also leads on ads (none vs shown) and update cadence (every 6 days vs every 4 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. GravityMan sells 4 one-off in-app purchases and High Octane! sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

GravityMan holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: GravityMan has 1.2K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 60% of GravityMan's written reviews are positive against 44% of High Octane!'s.

GravityMan ships an update every 6 days, High Octane! every 4 months. The most recent releases landed on October 12, 2026 and September 28, 2026 respectively.
