Verdict
The clearest difference is price: 小灵龙App at Free against 737 CSFF's $2.99. 小灵龙App also leads on update cadence (monthly vs every 4 months) and ratings volume (12 vs 2). 737 CSFF's advantage is rating (5.0 vs 1.0) and ads (none vs shown). On in-app purchases and device support there is nothing between them.
