Dr Wants older app back

Current version of this app requires internet access and is less user friendly. Layout of figures, text, references are inferior to previous version. This current app is no longer as helpful. I wish I never updated to this version and wish I could revert to previous version.

Awesome Echocardiography App!

seahorse in laJolla

I find this to be a very sophisticated and comprehensive application. This app is not just about calculations; it contains tips and rationale for acquisition and measurement, references, diagrams, movies and via these items, almost the entire collection of the ASE's most important and trusted guidelines and standards documents are broken down into bite sized pieces for easy access by serious sonographers and echocardiographers worldwide. This is completely worth the price. t

Lost function


It used to be a great app with very rare crashes if at all until this last update. Now the app opens rarely. I have tried deleting and reloading many times but still the app would not open long enough to allow me to look up what I want to look up. The updates guidelines may have made the content better but if the app has lost function because of the update. This update has destroyed this once lovely and immensely useful app.
