Welcome to the support and feedback page for EchoTools – a free iOS application intended for echocardiographers. This application unifies my interests in echocardiography, programming, and medical education. I started coding this app off-and-on when I was a fellow in 2018. Although I’m still learning how to program in Swift by trial-and-error, I’m using this opportunity to help consolidate point-of-care ultrasound (POCUS) videos, cardiac anatomic metrics, valve lesion grading criteria, etc., into a single application using Apple’s latest Xcode and Swift elements.

Please leave me feedback, recommendations, and glitches you face in the comments section below! Keep in mind that I make no promises that any or all bugs will be addressed, nor do I guarantee the accuracy of the data in the app (although I try my VERY best). Furthermore, EchoTools should NOT be used as a substitute for a licensed echocardiographer’s final interpretation. If you’re interested in the references I used, check out the “About” tab from within the app.

Thank you for checking out my app! 🙂


If you’d like to contribute an echo video clip to EchoTools with a teaching vignette, contact me for more information with the case! You’ll get full credit for the contribution. 🙂

  1. I’m a recently graduated Navy anesthesiologist who loves this app! Especially the cool pathology you included. Very interested in pursuing fellowships in critical care or CT and your blog has definitely fueled this desire. Thanks for everything.
