# Mud Engineer vs Max Drilling

The clearest difference is price: Max Drilling at Free against Mud Engineer's $2.99. Max Drilling also leads on rating (3.2 vs 1.0) and update cadence (every 4 months vs every 34 months). Mud Engineer's advantage is review sentiment (100% vs 63%) and chart position (#71 vs unranked). On ads, in-app purchases and device support there is nothing between them.

Max Drilling is free to download; Mud Engineer costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Max Drilling holds the better App Store score, 3.2 against 1.0. That said, the two scores are not equally well evidenced: Max Drilling has 22 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Mud Engineer's written reviews are positive against 63% of Max Drilling's, so the app with the better star average is not the one people write more warmly about.

Mud Engineer ships an update every 34 months, Max Drilling every 4 months. The most recent releases landed on September 17, 2026 and September 23, 2026 respectively.
