IPTV Core is a free multimedia application developed by Alexander Sofronov for Android devices. This app is intended to be used for creating customized IPTV apps for providers. It works similarly to the IPTV app, but it is easier to use and doesn't require complicated settings.

The app supports M3U and XSPF playlists and provides a grid, list, or tile view of TV channels. It also supports EPG in XMLTV and JTV formats. However, users cannot add custom playlists, and the channels list is obtained from the caller app. Additionally, there are no UDP proxy settings available.

If you want to add localization for your language, you can contact the developer via email. Keep in mind that this app doesn't have a launcher and cannot be launched directly. It should be launched by other apps, so install it only if some other app asks for it.

Overall, IPTV Core is a useful app for providers who want to create customized IPTV apps without complicated settings.
