BP18 App is the official mobile application of the Pestszentlőrinc-Pestszentimre Municipality in the 18th district of Budapest. The app offers access to local news, programs, pictures, videos, service advertisements, and announcements. One of the standout features is the new City Card module, allowing users to make purchases at a discount from city card partners.

Upon registration for a city card, users receive a unique virtual city card with a QR code, redeemable at discount points. Users can accumulate points through purchases, track scores in player form, and explore city card-accepting places on a map. The push messaging system has been enhanced to keep users informed about important city events seamlessly.
