Bad app. The buffering is unacceptable. It's impossible to get through a 30 minute exercise in 30 minutes because both audio and video stops to buffer every 5 seconds and then buffers for 8-20 seconds. Other streaming services have no problems, so it's not the WiFi or the phone. Adding video when they can't even provide uninterrupted audio is simply ludicrous. And since downloading mostly isn't offered, this app is in effect useless and the experience is the opposite of relaxing.
