The clearest difference is in-app purchases: EHA Guidelines at none against VTE Calc's 1. EHA Guidelines also leads on rating (5.0 vs 4.8). VTE Calc's advantage is update cadence (every 2 days vs every 23 months) and iOS requirement (9.0 vs 13.0). On price, ratings volume, ads and monetization model there is nothing between them.
