Verdict
The clearest difference is monetization model: SteelSolve at free against Construction Pro's freemium. SteelSolve also leads on ratings volume (7 vs 1). Construction Pro's advantage is update cadence (every 10 days vs monthly). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. SteelSolve sells 1 one-off in-app purchase and Construction Pro sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for SteelSolve against 5.0 for Construction Pro. That said, the two scores are not equally well evidenced: SteelSolve has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
SteelSolve ships an update monthly, Construction Pro every 10 days. The most recent releases landed on October 24, 2026 and October 28, 2026 respectively.
