Verdict
The clearest difference is price: F Numbers at Free against Pipedata's $12.99. F Numbers also leads on rating (5.0 vs 4.7). Pipedata's advantage is update cadence (weekly vs every 13 months) and iOS requirement (11.0 vs 13.0). On ratings volume, ads, in-app purchases and device support there is nothing between them.
