Barcelona Digital City

53% of people will leave a web page if it takes more than three seconds to open. A page's loading time and ease of access are essential in order to guarantee the success of an app or a website. Progressive web applications are applications that take advantage of the most advanced characteristics of current web browsers and adapt to different screens and devices. They also allow secure connections to be established to send and recover data, and link specific content. Progressive web applications follow the example of the most innovative digital journalism media.

Coinciding with the 2017 Mobile World Congress, Barcelona City Council set in motion its first  progressive web app in order to publicise the city's points of interest, published under creative commons licence. This web app is part of Barcelona City Council's new digital communication strategy for mobile channels, included in the Barcelona Digital City Plan. This is a commitment to open standards, open-source software and the use of cross-platform technologies.
