# ElbowData vs Sheet Metal Calculator Pro

The clearest difference is review sentiment: ElbowData at 75% against Sheet Metal Calculator Pro's 0%. ElbowData also leads on update cadence (every 2 months vs every 6 months) and monetization model (ad-supported vs free with in-app purchases). Sheet Metal Calculator Pro's advantage is rating (4.1 vs 3.0) and ads (none vs shown). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. ElbowData sells 1 one-off in-app purchase and Sheet Metal Calculator Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sheet Metal Calculator Pro holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: Sheet Metal Calculator Pro has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of ElbowData's written reviews are positive against 0% of Sheet Metal Calculator Pro's, so the app with the better star average is not the one people write more warmly about.

ElbowData ships an update every 2 months, Sheet Metal Calculator Pro every 6 months. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
