# Drilling Simulator 3 vs Mechanical Engineering Book

The clearest difference is price: Mechanical Engineering Book at $1.99 against Drilling Simulator 3's $49.99. Mechanical Engineering Book also leads on ratings volume (12 vs 1) and iOS requirement (10.0 vs 12.0). Drilling Simulator 3's advantage is rating (5.0 vs 4.7) and update cadence (every 2 months vs every 11 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

Drilling Simulator 3 costs $49.99 and Mechanical Engineering Book $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Drilling Simulator 3 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mechanical Engineering Book has 12 ratings behind it against 1, so its average is the more settled of the two.

Drilling Simulator 3 ships an update every 2 months, Mechanical Engineering Book every 11 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
