Verdict

The call

The clearest difference is monetization model: ECG Notes at free with in-app purchases against ECG EKG Interpretation Mastery's subscription. ECG Notes also leads on review sentiment (50% vs 25%) and rating (4.7 vs 4.5). ECG EKG Interpretation Mastery's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). On price, in-app purchases and device support there is nothing between them.
