# ME2Go vs Mechanical Formula

The clearest difference is rating: Mechanical Formula at 4.7 against ME2Go's 3.0. Mechanical Formula also leads on ratings volume (34 vs 6). ME2Go's advantage is review sentiment (27% vs 0%) and update cadence (every 2 months vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ME2Go sells 10 one-off in-app purchases and Mechanical Formula sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mechanical Formula holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Mechanical Formula has 34 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 27% of ME2Go's written reviews are positive against 0% of Mechanical Formula'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 Formula every 4 months. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
