# Torque Tightening vs Piping Engineering Toolbox

The clearest difference is rating: Piping Engineering Toolbox at 3.7 against Torque Tightening's 2.0. Piping Engineering Toolbox also leads on update cadence (every 3 months vs every 9 months) and ratings volume (9 vs 1). Torque Tightening's advantage is in-app purchases (none vs 4) and review sentiment (67% vs 50%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Piping Engineering Toolbox sells 4 in-app purchases, starting at $1.99 per 7 days. Torque Tightening asks for nothing beyond the download.

Piping Engineering Toolbox holds the better App Store score, 3.7 against 2.0. That said, the two scores are not equally well evidenced: Piping Engineering Toolbox has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of Torque Tightening's written reviews are positive against 50% of Piping Engineering Toolbox's, so the app with the better star average is not the one people write more warmly about.

Torque Tightening ships an update every 9 months, Piping Engineering Toolbox every 3 months. The most recent releases landed on October 3, 2026 and September 24, 2026 respectively.
