# Pixel Stack vs GridGain

The clearest difference is rating: Pixel Stack at 4.7 against GridGain's 3.0. Pixel Stack also leads on ratings volume (230 vs 6). GridGain's advantage is in-app purchases (none vs 10) and update cadence (fortnightly vs every 6 weeks). On price, ads and device support there is nothing between them.

Both are free to download. Pixel Stack sells 10 one-off in-app purchases. GridGain asks for nothing beyond the download.

Pixel Stack holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Pixel Stack has 230 ratings behind it against 6, so its average is the more settled of the two.

Pixel Stack ships an update every 6 weeks, GridGain fortnightly. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
