EchoTools on iOS

ultrasonography reference app


I'm a firm proponent of free, open-access medical education (FOAMed). As such, this app will remain free to the public.


I use Apple's native Swift elements to create a fast, minimalistic user interface. The focus is on the content!


EchoTools is constantly updated with new information and updated guidelines from leading professional societies.

MD Programmer

I'm a full-time academic physician with extensive training in TEE and POCUS. I routinely utilize ultrasound in my OR and ICU practices.

About Me

I’m a Harvard-trained academic cardiothoracic anesthesiologist and cardiovascular critical care physician working in the Texas Medical Center. I divide my clinical time between the OR and ICU caring for critically ill patients, training residents and fellows, and fostering multidisciplinary collaboration. I also enjoy creating and curating free, open-access medical education (“FOAMed”) to distribute through social media, investing, studying, teaching, and all things tech!

My clinical interests include ultrasonography, mechanical circulatory support, RV dysfunction, ICU pharmacology, and advanced monitors.

EchoTools is a product of trial-and-error that I've been piecing together since my fellowship training. It unifies my interests in medical education, ultrasonography, and programming in a way that can hopefully be helpful to many! I write 100% of the code, so if you have any feedback, let me know.

CA2 on my echo rotation! Thank you for creating and offering this app for as a free resource! I am very excited to show my attending tomorrow in the OR.

CA-1 on cardiac rotation. This app is great as a reference while in the OR! I like how there are labels on the TEE images to help orient me.

It is very simple and useful. I love this app.


Thanks Rishi, I'm finding your app very handy to reference normal values whilst doing TOE in OT


This is a work of art and, as a senior Anesthesiology/Critical Care Resident-Cardiac Anesthesiologist to be, I've used it since the first version both in the OR and CVICU.
