I enjoy it because it has hands free scales, however many other apps also have those. I wish there was a way to skip that annoying coach explanation before each riff n run. It should be called "listen for awhile and then riff." Ive had the app for months I dont need an explanation EVERY time I use it. Also the "Gimme a Workout" section crashes in all four sections. My finger gets more of a workout restarting the app. Sheesh people please fix the bugs. I keep updating with no improvement. Im about to quit entirely.
