Verdict
The clearest difference is rating: Mark'd at 5.0 against JINS US's 1.7. Mark'd also leads on update cadence (every 2 weeks vs monthly). JINS US's advantage is ratings volume (6 vs 1) and iOS requirement (12.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
