# C/C++ vs Flowdia Diagrams

The clearest difference is rating: C/C++ at 4.5 against Flowdia Diagrams's 3.4. C/C++ also leads on review sentiment (86% vs 54%) and ratings volume (342 vs 66). Flowdia Diagrams's advantage is update cadence (every 6 weeks vs every 5 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. C/C++ sells 7 one-off in-app purchases and Flowdia Diagrams sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

C/C++ holds the better App Store score, 4.5 against 3.4. That said, the two scores are not equally well evidenced: C/C++ has 342 ratings behind it against 66, so its average is the more settled of the two. Written reviews point the same way: 86% of C/C++'s written reviews are positive against 54% of Flowdia Diagrams's.
