Great App!!

Ideal for 1st year cardiology fellows learning how to read echo! Definitely saves time for trainees who are still dependent on the chamber qualification guidelines for normal cutoffs. Some of the normal chamber size ranges need to be updated from 2015 ASE guidelines (supplemental table 3) but otherwise a great app.

Developer Response ,

I'll work on updating to the latest guidelines as soon as possible! Thanks for the great feedback!
