When I went to download this app it said it would provide access to some free live channels and an online DVR but all I seem to be getting our options to purchase things I'm confused about what's what

There are 2 apps. One is a live TV viewing app for $25, which will allow for viewing of live TV with a HDHomeRun tuner. The second app is free, but must be coupled with the DVR subscription. The DVR subscription can use a HDHomeRun tuner for OTA/cable broadcasts, or additionally with TV Everywhere credentials, or supplied IPTV custom channels.
