The best thing I like about this app is that it can identify my emotions from my facial expressions. It also detects my emotional state, which helps me to understand how I am feeling at any given time. Sometimes it gets confused when I'm happy but sad. I don't know if it's just because of the lighting or something else. I've noticed that sometimes it takes a while for the app to recognize my face. I use this app all the time, whenever I feel down, I take a picture with my phone. This app helps me to determine what emotion I'm feeling and why.
