# JSONDoc vs LogCat Analyzer

The clearest difference is rating: JSONDoc at 5.0 against LogCat Analyzer's 1.0. LogCat Analyzer's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (15.0 vs 18.6). On price, ratings volume, update cadence and ads there is nothing between them.
