# MaxiAP vs Giotto ScanTool

The clearest difference is update cadence: MaxiAP at every 3 weeks against Giotto ScanTool's every 3 months. MaxiAP also leads on iOS requirement (8.0 vs 14.0). Giotto ScanTool's advantage is ratings volume (44 vs 7). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Giotto ScanTool holds the better App Store score, 3.3 against 3.1. That said, the two scores are not equally well evidenced: Giotto ScanTool has 44 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 33% of MaxiAP's written reviews are positive against 31% of Giotto ScanTool's, so the app with the better star average is not the one people write more warmly about.

MaxiAP ships an update every 3 weeks, Giotto ScanTool every 3 months. The most recent releases landed on October 11, 2026 and October 14, 2026 respectively.
