I’m in a condo so I use my iPad for TrainerRoad and Zwift (though I’m thinking of canceling the latter). The TV is in front of but off to my left, as my trainer is setup on the side of the living room. It’s close enough to watch trash TV or play music. Used to pull the trainer to be centered in front with Zwift on the TV but moving it back and forth got old real quick, so I rearranged the whole living room.
I don’t like to run either on my phone because I use that for messaging and other entertainment or distractions while on the trainer.
