# arrhythmia vs ECG Practice

arrhythmia and ECG Practice both sit at 4.2 stars, but that hides the real split: 45% of arrhythmia's written reviews are positive against 0% of ECG Practice's. arrhythmia also leads on update cadence (every 3 weeks vs every 2 months) and chart position (#188 vs unranked). ECG Practice's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (15.6 vs 17.6).
