Web app push notification [closed]

Question

I'm going to make a web app using html5. The app are going to be able to send a push notification to the phone even if the web app isn't used. Is this possible?

Answer 1

This is not possible natively in browsers yet, though W3C standards for browser-based push notifications are finalizing this year.

The only options are to:

• wait for Apple, Google, etc to implement the W3C recommendations in their browsers (if I were to guess, probably late 2012, early 2013)
• have users install a native app that pushes notifications on behalf of your web app (like AlertRocket)
• use SMS text messages through an SMS subscription service
