The app and the content are free, the workout programs are amazing resources - when the app actually works long enough for you to access them.
The app is so consistently buggy that it renders the content inaccessible most of the time. Most of the time, the app won’t even allow you advance past the opening splash page. And if it does, it freezes, crashes, or fails to save any data you input.
Great content, great workouts, great programs, great motivation, absolutely ABYSMAL app.
