Verdict
The clearest difference is in-app purchases: Osmo Numbers at none against Kidle's 1. Osmo Numbers also leads on ratings volume (145 vs 23). Kidle's advantage is review sentiment (62% vs 33%) and update cadence (every 2 weeks vs every 2 months). On price, rating, ads and monetization model there is nothing between them.
