# Watch ECG Pro vs ECG AI

The clearest difference is rating: Watch ECG Pro at 4.4 against ECG AI's 1.0. Watch ECG Pro also leads on review sentiment (25% vs 0%) and ratings volume (64 vs 2). ECG AI's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, monetization model 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 and ECG AI sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Watch ECG Pro holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: Watch ECG Pro has 64 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 25% of Watch ECG Pro's written reviews are positive against 0% of ECG AI's.

Watch ECG Pro ships an update every 2 months, ECG AI every 3 weeks. The most recent releases landed on November 7, 2026 and November 9, 2026 respectively.
