Hotstar is a site in which you can watch live tv and shows. It is owned by Star india which has many channels like star plus, star sports etc. It is also available in many indian languages like bengali, telugu, tamil etc. including hindi and english.
It also has an app on appstore and playstore which you can download for free. The interface of the app is very good and easy to use. It provides latest shows and also broadcasts live coverage of cricket matches.
The only downside is that it has a few ads at the starting of the video which sometimes could be annoying. There are also international shows which you can watch on it.
Overall, it is a great app for those who are busy and could not watch their favourite shows on time.
