Basically useless on your phone since they don't allow the good quality even after setting it to maximum data and highest quality. I always noticed that everything looks worse on my phone. Turns out, when I compared the downloaded episodes on the desktop app versus the mobile app, I noticed that the mobile versions episodes are just 150 MB or so. And, the desktop versions are 1.1 GB and above! No wonder. I have a flagship phone with an AMOLED screen, so, screen quality isn't the issue here.
