# MedKrok vs ECG Trainer

The clearest difference is review sentiment: MedKrok at 50% against ECG Trainer's 0%. MedKrok also leads on rating (4.6 vs 1.0) and ratings volume (34 vs 1). ECG Trainer's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 3 weeks vs every 5 weeks). On price, ads, in-app purchases and iOS requirement there is nothing between them.
