Mobile Web Apps

Web apps are not real applications; they are really websites that, in many ways, look and feel like native applications, but are not implemented as such. They are run by a browser and typically written in HTML5. Users first access them as they would access any web page: they navigate to a special URL and then have the option of “installing” them on their home screen by creating a bookmark to that page. Web apps became really popular when HTML5 came around and people realized that they can obtain native-like functionality in the browser. Today, as more and more sites use HTML5, the distinction between web apps and regular web pages has become blurry. In 2011 Financial Times withdrew its native app from Apple’s App Store to circumvent subscription fees and maintain closer connection with their subscribers. Instead, it came out with an iPhone web app (app.ft.com):


Its web app is, in many ways, hard to distinguish from a native app. For instance, there are no visible browser buttons or bars, although it runs in Safari (when accessed from an iPhone). Users can swipe horizontally to move on to new sections of the app. And, due to browser caching, it’s even possible to read the newspaper offline.

These are all features that are available in HTML5. Also available are the GPS, the tap-to-call feature, and, there is talk about a camera API, although I haven’t seen any web app (or web page) that takes advantage of it so far. There are, however, native features that remain inaccessible (at least from now) in the browser: the notifications, running in the background, accelerometer information (other than detecting landscape or portrait orientations), complex gestures.

Of course, one can argue that many apps (native or otherwise) do not take advantage of those extra features anyhow. But if you really need those native features, you’ll have to create a native app or, at least, a hybrid app.
