Verdict
The clearest difference is rating: PB at 3.9 against Functional Bodybuilding's 2.9. PB also leads on review sentiment (40% vs 26%) and iOS requirement (14.0 vs 16.0). Functional Bodybuilding's advantage is in-app purchases (none vs 2) and ratings volume (146 vs 13). On price, update cadence, ads and device support there is nothing between them.
