Verdict
The clearest difference is update cadence: Kotlin Tutorial at every 4 weeks against Codalingo's every 4 months. Kotlin Tutorial also leads on rating (4.7 vs 4.5) and iOS requirement (12.0 vs 15.6). Codalingo's advantage is ratings volume (24 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.
