# Pipedata vs Piping

The clearest difference is price: Pipedata at Free against Piping's $9.99. Pipedata also leads on rating (4.3 vs 1.0) and update cadence (every 3 weeks vs every 10 months). Piping's advantage is review sentiment (67% vs 52%) and iOS requirement (9.0 vs 11.0). On ads, in-app purchases and device support there is nothing between them.

Pipedata is free to download; Piping costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Pipedata holds the better App Store score, 4.3 against 1.0. That said, the two scores are not equally well evidenced: Pipedata has 39 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 52% of Pipedata's written reviews are positive against 67% of Piping's, so the app with the better star average is not the one people write more warmly about.

Pipedata ships an update every 3 weeks, Piping every 10 months. The most recent releases landed on September 19, 2026 and September 23, 2026 respectively.
