# Pathophysiology Review vs arrhythmia

The clearest difference is price: arrhythmia at Free against Pathophysiology Review's $7.99. arrhythmia also leads on rating (4.2 vs 2.3) and update cadence (every 3 weeks vs every 34 months). Pathophysiology Review's advantage is in-app purchases (none vs 3). On ads, chart position, device support and iOS requirement there is nothing between them.

arrhythmia is free to download; Pathophysiology Review costs $7.99 up front. arrhythmia sells 3 in-app purchases, starting at $2.99 per month. Pathophysiology Review asks for nothing beyond the download.

arrhythmia holds the better App Store score, 4.2 against 2.3. That said, the two scores are not equally well evidenced: arrhythmia has 111 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 25% of Pathophysiology Review's written reviews are positive against 45% of arrhythmia's.
