Verdict
The clearest difference is ads: Chamka at none against 클래스연구소's shown. Chamka also leads on monetization model (free vs ad-supported). 클래스연구소's advantage is update cadence (daily vs monthly) and iOS requirement (11.0 vs 14.0). On price, in-app purchases and device support there is nothing between them.
