It’s not a web app (not certain why op requested that bit),
I’m looking for something I can use on my desktop and my phone. I currently use Windowz but slowly migrating to Linux.
I guess it doesn’t necessarily need to be web enabled as long as there is a way to use it in Windows and Linux.
My last two TVs were dumb ones.
It is getting harder find dumb TVs because the smart stuff included with most TVs subsidizes keeping the initial price low. Manufactures are betting millions of dollars purchasers will sign up for the monthly apps.
