Jiotv is one of the awesome app where you can watch mostly all the leading channels for free even sometimes you can watch certain shows or movies before they come on tv on jiotv .
I personally like this app very much as it is free and give me many options to watch different channels either it is music movies sports reality shows etc just in the one app in my phone
but I think its major drawback is that it only works on jio and not on any other sim so for jio users its awesome but for others it does nt work so you can face problem there
