Verdict

The call

The clearest difference is in-app purchases: COPD at none against VTE Calc's 1. COPD also leads on rating (5.0 vs 4.8). VTE Calc's advantage is update cadence (every 2 days vs every 2 months) and ratings volume (4 vs 1). On price, ads, monetization model and device support there is nothing between them.
