Verdict
The clearest difference is review sentiment: Pipe Sizer at 100% against Pump Calculator's 0%. Pipe Sizer also leads on rating (4.8 vs 1.0) and update cadence (every 17 months vs every 41 months). Pump Calculator's advantage is price ($2.99 vs $12.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Pipe Sizer costs $12.99 and Pump Calculator $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Pipe Sizer holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Pipe Sizer has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Pipe Sizer's written reviews are positive against 0% of Pump Calculator's.
Pipe Sizer ships an update every 17 months, Pump Calculator every 41 months. The most recent releases landed on October 7, 2026 and October 1, 2026 respectively.
