Verdict
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.
