### ***** "Thank you."

-- YashSenghani, 2022-01-12

### ***** "Excellent"

-- Taha saeed £, 2021-06-07

### ***** "Great resource for anesthesia residents"
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.
-- ska020, 2021-03-10

### ****- "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.
