# Blue Linea vs Geometry Dash SubZero

The clearest difference is rating: Geometry Dash SubZero at 4.5 against Blue Linea's 3.5. Geometry Dash SubZero also leads on in-app purchases (none vs 6) and update cadence (every 10 months vs every 65 months). Blue Linea's advantage is ads (none vs shown) and iOS requirement (8.0 vs 15.0). On price, review sentiment and device support there is nothing between them.

Both are free to download. Blue Linea sells 6 one-off in-app purchases. Geometry Dash SubZero asks for nothing beyond the download.

Geometry Dash SubZero holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Geometry Dash SubZero has 85K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 88% of Blue Linea's written reviews are positive against 82% of Geometry Dash SubZero's, so the app with the better star average is not the one people write more warmly about.

Blue Linea ships an update every 65 months, Geometry Dash SubZero every 10 months. The most recent releases landed on November 1, 2026 and November 13, 2026 respectively.
