Podcast-Type App Development

This may be beyond the scope of what is possible, but I would like to develop an app that would allow downloading of company videos to the device.

The objective being some of our videos are helpful on jobsites, but our customers don't always have internet/data access. If they could select from a list of videos to be downloaded, then have the capability to remove them from the device as well. That would be ideal.

You might ask why not just make a web page and have them available for download, then the user could just drop them onto their device? The problem there is that we need to have an interface to show more detailed descriptions of the videos and would like to control the look of the interface.

My thought was a podcast-type app that is dedicated to our video content.

Could someone possibly point me in the right direction?

Thanks!
