Don't bother if you have a Beats Fit. App has nothing for it. It's just a waste of space. No bass boast, no options for different sounds, nothing. Shows what your buttons do and that's all. Oh, you can register your headphones. Should've gotten Beats Fit Pro if the store had them. Maybe more options then in app. Don't know. But it's a waste of space on my phone as is right now. Wish there were sound settings like my Samsung Galaxy Buds app.
