2 apps on App Store, which one should I be using on all my Apple TVs

Hi, in the apple App Store there are 2 apps listed for you, channels, and channels DVR.. which one is the best to use? having 2 is confusing.. both seem to work exactly the same? Thanks

They are essentially the same app. The "Channels DVR" app requires a DVR server to work, and has no cost. The "Channels" app does not require a DVR server, but has an associated one-time purchase fee (except for iOS, where both are free).

One is our stand alone paid app that requires no subscription.

The other is a free version that only works with active Channels Plus subscriptions.
