Verdict
The clearest difference is review sentiment: KMSU at 100% against Watchbell's 25%. KMSU also leads on rating (5.0 vs 2.5) and ratings volume (18 vs 2). Watchbell's advantage is update cadence (daily vs every 6 months) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
