The most important thing I like about this app is that it allows me to listen to my heart sounds in real time, which would be impossible with other apps or devices! It's also easy enough for anyone (even those who have never used an echocardiogram machine before) to use without any training at all. There are some parts of using this device where there could potentially be more user-friendly features/options available, but overall everything works fine and has been very helpful thus far as part of our daily workflow! We've found ourselves referring back to previous exams we'd taken just so we can hear what was happening during certain portions of them!
