Verdict
The clearest difference is review sentiment: Fluid Mechanics Pack at 100% against C Reference's 55%. Fluid Mechanics Pack also leads on rating (5.0 vs 2.0) and update cadence (every 9 months vs every 24 months). C Reference's advantage is price ($0.99 vs $3.99) and chart position (#197 vs unranked). 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
C Reference costs $0.99 and Fluid Mechanics Pack $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Fluid Mechanics Pack holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: Fluid Mechanics Pack has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 55% of C Reference's written reviews are positive against 100% of Fluid Mechanics Pack's.
C Reference ships an update every 24 months, Fluid Mechanics Pack every 9 months. The most recent releases landed on August 30, 2026 and September 18, 2026 respectively.
