For OAN, there is a free OANN: Live Breaking app. There is also KlowdTV that broadcasts OANN along with six or seven other shows for $4.99/mo and they have phone apps.
There are also apps for FireTV, Roku, and AppleTV if you don’t have a smart phone. There is no contract for KlowdTV so you can cancel any time if you decide that you aren’t getting your money’s worth.
