# arrhythmia vs ADMS

The clearest difference is rating: ADMS at 5.0 against arrhythmia's 4.2. ADMS also leads on in-app purchases (none vs 3) and iOS requirement (12.0 vs 17.6). arrhythmia's advantage is update cadence (every 3 weeks vs every 5 months) and ratings volume (111 vs 1). 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. ADMS asks for nothing beyond the download.

ADMS holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: arrhythmia has 111 ratings behind it against 1, so its average is the more settled of the two.

arrhythmia ships an update every 3 weeks, ADMS every 5 months. The most recent releases landed on September 21, 2026 and July 7, 2026 respectively.
