Verdict

The call

The clearest difference is review sentiment: QT ECG at 100% against Watch ECG Pro's 25%. QT ECG also leads on in-app purchases (none vs 3) and ads (none vs shown). Watch ECG Pro's advantage is rating (4.4 vs 3.4) and ratings volume (64 vs 5). On price, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Watch ECG Pro holds the better App Store score, 4.4 against 3.4. That said, the two scores are not equally well evidenced: Watch ECG Pro has 64 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of QT 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.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
