Dont waste your time
I am currently in ASL 1 at my High School so I wanted to get an app to practice with. I got this app and thought it was real ASL, not PSL until I saw some vocabulary that our deaf teacher uses often. I am disappointed and feel like this was a waste of time for me.
TL;DR: This is PSL, not ASL so verify any signs you learn from this.
