# ME2Go vs Mechanical Engineering Book

The clearest difference is price: ME2Go at Free against Mechanical Engineering Book's $1.99. ME2Go also leads on update cadence (every 2 months vs every 11 months) and review sentiment (27% vs 0%). Mechanical Engineering Book's advantage is rating (4.7 vs 3.0) and in-app purchases (none vs 10). On ratings volume, ads, device support and iOS requirement there is nothing between them.

ME2Go is free to download; Mechanical Engineering Book costs $1.99 up front. ME2Go sells 10 one-off in-app purchases. Mechanical Engineering Book asks for nothing beyond the download.

Mechanical Engineering Book holds the better App Store score, 4.7 against 3.0. Both are backed by a comparable volume of ratings — 6 and 12 respectively. Written reviews complicate that: 27% of ME2Go's written reviews are positive against 0% of Mechanical Engineering Book's, so the app with the better star average is not the one people write more warmly about.

ME2Go ships an update every 2 months, Mechanical Engineering Book every 11 months. The most recent releases landed on October 4, 2026 and October 1, 2026 respectively.
