Namma Bengaluru Smart Parking (NBSP) is a free Android app developed by PARKING4SURE that allows users to book and pay for parking through their mobile devices. The app is designed to be intuitive, with a simple three-click process for booking a parking spot.

Users have the option to log in as a registered user or a guest, with guest users required to provide personal information such as their name, phone number, and email address at the time of booking confirmation and payment. Additionally, users can log in using their Facebook or Google+ accounts.

The app also features a Google map that displays all available parking locations near the user's current location. Users can add one or more vehicles to their cart, as well as add-on services like valet parking. NBSP also allows users to use promo codes to avail discounts and pay using their wallet or bank account.

Users can earn loyalty points by referring a friend and view their past and upcoming bookings. They can also cancel a booking if needed and provide feedback on a parking spot, which can be shared on Facebook and Google+.
