It is an online app for ordering food. I have heard about this app from my friend when I created a new account in this app with my friends referral code I got a voucher of hundred rupees and then we used it for purchase of chicken biriyani worth rs.200.
And got a discount of rupees hundred the service was fast enough and the app is Comfortable to use, it even shows the how far our order has processed and ones its dispatched we can track the location of the delivery boy. so it is pretty easy to order and use swiggy and moreover they have many restaurants to choose from.
