# Piping and Flange Handbook vs Structural Engineering Calc.

The clearest difference is rating: Structural Engineering Calc. at 4.5 against Piping and Flange Handbook's 3.5. Structural Engineering Calc. also leads on price ($5.99 vs $8.99) and ratings volume (21 vs 2). Piping and Flange Handbook's advantage is review sentiment (39% vs 0%) and update cadence (monthly vs every 10 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

Piping and Flange Handbook costs $8.99 and Structural Engineering Calc. $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Structural Engineering Calc. holds the better App Store score, 4.5 against 3.5.
