Verdict
The clearest difference is review sentiment: ThinkEasy at 100% against KDIAG's 31%. ThinkEasy also leads on rating (5.0 vs 3.3) and iOS requirement (9.0 vs 17.0). KDIAG's advantage is update cadence (fortnightly vs every 5 months) and ratings volume (20 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
