# Steam Pad vs Mechanical Engineering Toolkit

The clearest difference is rating: Mechanical Engineering Toolkit at 4.8 against Steam Pad's 3.7. Mechanical Engineering Toolkit also leads on ratings volume (64 vs 3) and device support (4 vs 2). Steam Pad's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Steam Pad sells 1 one-off in-app purchase and Mechanical Engineering Toolkit sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mechanical Engineering Toolkit holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Mechanical Engineering Toolkit has 64 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of Steam Pad's written reviews are positive against 57% of Mechanical Engineering Toolkit's, so the app with the better star average is not the one people write more warmly about.

Steam Pad ships an update every 9 days, Mechanical Engineering Toolkit every 8 days. The most recent releases landed on June 1, 2026 and September 24, 2026 respectively.
