# ECG Notes vs ECG+ | Your Watch ECG Reader

The clearest difference is ads: ECG+ | Your Watch ECG Reader at none against ECG Notes's shown. ECG+ | Your Watch ECG Reader also leads on update cadence (every 10 days vs every 3 months) and ratings volume (2.5K vs 12). ECG Notes's advantage is rating (4.7 vs 4.5) and iOS requirement (13.0 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. ECG Notes sells 1 one-off in-app purchase and ECG+ | Your Watch ECG Reader sells 5 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ECG Notes holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: ECG+ | Your Watch ECG Reader has 2.5K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 50% of ECG Notes'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.

ECG Notes ships an update every 3 months, ECG+ | Your Watch ECG Reader every 10 days. The most recent releases landed on August 12, 2026 and October 1, 2026 respectively.
