IPTV Pro is a free M3U player for iOS devices. It works with all providers that use the M3U format. It also supports Chromecast and Air Play.

The best thing about this app is that it lets you add multiple M3U playlists at the same time, and you can switch between them as you like. It lets you create multiple groups of your favourite channels and movies, so you can browse through them easily.

The Electronic Program Guide (EPG) is available, so you can know what's currently playing and what's coming up for up to a week.
