TiVimate

Keep in mind that a player like tivimate is just that, a player, it doesn't come with any service. You will need to subscribe to a IPTV service to actually get channels. I have seen several posts lately by noobs that purchase tivimate and then are surprised that they can't watch TV..

I prefer tivimate

Hands down, TiviMate is the best IPTV player you can get

IMPlayer

Tivimate beats them all.

OTT Navigator for the win... Try it, you won't regret

Try CosmiDVR it's an addon for "Live Channels" and you watch, Rewind/Pause/Fwd and Record IPTV using "Live Channels" the internal TV Player of Nvidia Shield.

I am looking to buy fire stick or MI stick for playing XCIPTV or tivimate iptv in my LG smart tv. In LG content store bothering the apps are not available. Can you suggest me

Haven't tried TiVimate but it looks pretty nice. I have a different setup that I love though - Kodi + TvHeadend PVR plugin.

You need to setup TvHeadend on another machine but you get a full-on DVR system with an excellent Kodi-based TV Guide and scheduler. Plus you can install Kodi on every Android, Windows and Linux device you have and access all the channels and recordings from all of them :)

If you don't want the hassle of setting up the DVR backend, you can use Kodi with the SimpleIPTV plugin and just use it for live TV and Program Guide. Still pretty good, and completely free.
