# EchoCalc vs 3D Heart Anatomy

The clearest difference is review sentiment: EchoCalc at 49% against 3D Heart Anatomy's 0%. EchoCalc also leads on price (Free vs $6.99) and update cadence (monthly vs every 4 months). 3D Heart Anatomy's advantage is rating (5.0 vs 2.3) and in-app purchases (none vs 3). On ads there is nothing between them.

EchoCalc is free to download; 3D Heart Anatomy costs $6.99 up front. EchoCalc sells 3 one-off in-app purchases. 3D Heart Anatomy asks for nothing beyond the download.

3D Heart Anatomy holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: EchoCalc has 23 ratings behind it against 1, 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 3D Heart Anatomy's, so the app with the better star average is not the one people write more warmly about.

EchoCalc ships an update monthly, 3D Heart Anatomy every 4 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
