# EchoCalc vs Dr ECG

The clearest difference is review sentiment: EchoCalc at 49% against Dr ECG's 0%. EchoCalc also leads on ratings volume (23 vs 2). Dr ECG's advantage is rating (3.0 vs 2.3) and in-app purchases (none vs 3). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. EchoCalc sells 3 one-off in-app purchases. Dr ECG asks for nothing beyond the download.

Dr ECG holds the better App Store score, 3.0 against 2.3. That said, the two scores are not equally well evidenced: EchoCalc has 23 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 49% of EchoCalc's written reviews are positive against 0% of Dr ECG's, so the app with the better star average is not the one people write more warmly about.

EchoCalc ships an update monthly, Dr ECG every 6 weeks. The most recent releases landed on August 26, 2026 and June 1, 2026 respectively.
