The clearest difference is price: Overlap at Free against KDM Inspector's $2.99. Overlap also leads on rating (4.8 vs 4.0) and update cadence (every 3 months vs every 38 months). KDM Inspector's advantage is review sentiment (100% vs 67%). On ads and in-app purchases there is nothing between them.

Written reviews complicate that: 100% of KDM Inspector's written reviews are positive against 67% of Overlap's, so the app with the better star average is not the one people write more warmly about.
