# MyZio vs ECG+ | Your Watch ECG Reader

The clearest difference is in-app purchases: MyZio at none against ECG+ | Your Watch ECG Reader's 5. MyZio also leads on rating (4.8 vs 4.5) and ratings volume (69K vs 2.6K). ECG+ | Your Watch ECG Reader's advantage is update cadence (every 9 days vs every 6 months) and review sentiment (64% vs 53%). On price, ads, chart position and device support there is nothing between them.

Both are free to download. ECG+ | Your Watch ECG Reader sells 5 in-app purchases, starting at $9.99 per month. MyZio asks for nothing beyond the download.

MyZio holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: MyZio has 69K ratings behind it against 2.6K, so its average is the more settled of the two. Written reviews complicate that: 53% of MyZio's written reviews are positive against 64% of ECG+ | Your Watch ECG Reader's, so the app with the better star average is not the one people write more warmly about.

MyZio ships an update every 6 months, ECG+ | Your Watch ECG Reader every 9 days. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
