I am creating an HTML5 offline web app for use on iOS and Android.
Is there a mechanism for notifying the user that an update is available - e.g., a red dot on the application's shortcut icon? If there isn't, would I be able to achieve this maybe with push notifications or some other way?
I understand that I can use the manifest file to declare which files the app should attempt to update from the server - but my client is asking if the app would be able to visually notify to the user of the need to update.
