Verdict
The clearest difference is rating: NK Logbook at 3.8 against RowingCoach's 3.3. NK Logbook also leads on review sentiment (63% vs 38%) and iOS requirement (13.0 vs 17.0). RowingCoach's advantage is update cadence (every 2 months vs every 4 months) and ratings volume (117 vs 12). On price, ads, in-app purchases and monetization model there is nothing between them.
