It 1000% looks shady af, I felt the same, but I’ve been using it for like 5 years now with no issues. Can always run it in an emulator like Bluestacks on PC and use it like that with fewer worries. That being said lemme make sure that’s the right url you linked

Edit: the official website listed in the app is https://www.livenettv.mn/. The github you linked may be someone elses clone of it or attempt to fake it. The 404ing website they have listed isn’t the correct url for the app (or might be an old url)

Idk if you’re being sarcastic or anything, but I’ll actually answer the question. Apologies if this is unnecessary.

You can hook up an Over the Air antenna (like one listed in this article ), which you can hook up directly to a lot of TVs I think.

Instead of connecting to your TV, you can get an IP Tv Tuner, like HDHomeRun. This let’s you connect the antenna to your home network and access the feed from your computer and their app. It also provides a video stream that Jellyfin and Plex (I’d bet Kodi as well) can access.
