# arrhythmia vs EKGSmart

The clearest difference is rating: EKGSmart at 5.0 against arrhythmia's 4.1. EKGSmart also leads on in-app purchases (none vs 3) and iOS requirement (15.1 vs 17.6). arrhythmia's advantage is ratings volume (113 vs 1) and update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. arrhythmia sells 3 in-app purchases, starting at $2.99 per month. EKGSmart asks for nothing beyond the download.

EKGSmart holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: arrhythmia has 113 ratings behind it against 1, so its average is the more settled of the two.

arrhythmia ships an update every 3 weeks, EKGSmart every 2 months. The most recent releases landed on October 29, 2026 and October 25, 2026 respectively.
