It's definitely worth a look. It has a bunch of stuttering books, masterclass videos, thousands of coaching videos, group calls, speech therapy with ex-stutterers, hundreds of testimonials, etc. It has a bunch of resources and I thank who ever made that app because it's helping my speech tremendously and I won't ever quit. I feel sorry for those who don't give it the old college try because if you work at it, it will change your life. It goes beyond stuttering really.
