# mini ECG vs Watch ECG Pro

The clearest difference is rating: Watch ECG Pro at 4.4 against mini ECG's 2.8. Watch ECG Pro also leads on ratings volume (63 vs 5) and iOS requirement (12.0 vs 14.0). mini ECG's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Watch ECG Pro sells 3 in-app purchases, starting at $6.99 per 7 days. mini ECG asks for nothing beyond the download.

Watch ECG Pro holds the better App Store score, 4.4 against 2.8. That said, the two scores are not equally well evidenced: Watch ECG Pro has 63 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 56% of mini ECG's written reviews are positive against 25% of Watch ECG Pro's, so the app with the better star average is not the one people write more warmly about.

mini ECG ships an update every 3 months, Watch ECG Pro every 2 months. The most recent releases landed on October 2, 2026 and October 3, 2026 respectively.
