The android app by Bharat Gas, one of the major distributors, can be used to book a cylinder, know your distributor, talk to the customer care, rate a distributor, keep a tab on order history and perform various actions.
Indane has another app which does pretty much the same things. Users have been complaining of a login problem though.
The app by Hindustan Petroleum, called HP Gas on the store and it requires you to register on the Hindustan Petroleum website before you can start using it. This can be used to book cylinders, make complaints etc.
The government has also launched a pilot project on distributor portability. Basically, if you don’t like your distributor, you can use an online portal to move to another distributor. The project was launched in Chandigarh as a pilot on Friday and will be extended to 25 more districts this year.
