Verdict

The call

The clearest difference is review sentiment: Wormax.io at 85% against King Justice's 11%. Wormax.io also leads on rating (4.7 vs 3.1) and ratings volume (4.6K vs 63). King Justice's advantage is update cadence (every 2 days vs every 3 weeks) and iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
