Books!
It all depends on where I am reading
I keep a paper book in the door pocket of the car (usually doctrinal literature) for when I have to wait somewhere
I also have a paper book in the bathroom for when I go poop or lay in the sauna
If I read in the hot tub, I read on my phone
I have a Dutch library app on there and do most of my reading on there, because it allows me to read in Dutch
Then audiobooks...they are seasonal
And every winter I go through a few of them in my plow truck
