# Engineering Unit Converter vs Steel Profiles

The clearest difference is rating: Steel Profiles at 4.7 against Engineering Unit Converter's 4.3. Steel Profiles also leads on update cadence (every 10 days vs monthly) and ratings volume (331 vs 86). Engineering Unit Converter's advantage is review sentiment (82% vs 72%) and iOS requirement (11.2 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Engineering Unit Converter sells 1 one-off in-app purchase and Steel Profiles sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Steel Profiles holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 86 and 331 respectively. Written reviews complicate that: 82% of Engineering Unit Converter's written reviews are positive against 72% of Steel Profiles's, so the app with the better star average is not the one people write more warmly about.

Engineering Unit Converter ships an update monthly, Steel Profiles every 10 days. Both last shipped on October 23, 2026.
