Play your remote IPTV lists (m3u) in the Apple TV.
In the free version you could use the app features for adding and playing lists/channels but you could not use the search option. Each time you reboot the app you'll need to add the lists again.
If you want to contribute to the app development and unlock search channels & saving list functionality you can Go Pro from More tab inside of the app.
This app is not providing any IPTV list, it's intended to be used with your own ones.
