This app has good content, but the UI needs some serious attention in ease of use. Buttons are placed randomly. Most will want to use this while driving so setting it up quickly at a stoplight should be the metric for how long it takes to go through a setup workflow. There is no logic to how the playlists work. This will be a great tool when the UI issues are fixed. Some of this may be mitigated by more comprehensive help screens.
Update: they dont respond to email and there have been no updates since the first release. Avoid.
