Verdict
The clearest difference is price: DIS Enum at Free against ProMasters Only's $69.99. DIS Enum also leads on rating (5.0 vs 4.5) and review sentiment (100% vs 79%). ProMasters Only's advantage is ratings volume (21 vs 2) and chart position (#88 vs unranked). On ads, in-app purchases and device support there is nothing between them.
