Verdict
The clearest difference is price: FastGoal at Free against AllyFast's $0.99. FastGoal also leads on update cadence (every 2 weeks vs monthly) and iOS requirement (15.1 vs 18.2). AllyFast's advantage is ads (none vs shown) and ratings volume (18 vs 1). On rating, review sentiment, in-app purchases and device support there is nothing between them.
