Official Add To Homescreen plugin displays a callout to mobile users inviting them to add the website to the home screen.
The plugin opens a message inviting the mobile user to add the application to the home screen. This is currently supported on iOS and Mobile Chrome. While other devices have the ability to bookmark any website to the home screen, only iOS and Mobile Chrome have a straightforward way to do it. Windows Phone support is planned for a future release.
To enhance performance and reduce complexity I'm supporting the latest two OS version for each device only.
Add To Homescreen development started when Apple introduced the
apple-mobile-web-app-capable meta tag and
standalone mode with it. It was a great news for web developers who had the opportunity to release full screen web applications (and not just websites). The script evolved over time and extended to a more general purpose use case.
It is important to note that there's no native event we could hook to to know when a user actually added the page to the homescreen. That's also the reason why this script has become so complicated despite the apparent simple task it has to accomplish.
Unless you explicitly developed your application to be
mobile-web-app-capable, this script can't do miracles and all the alternative solutions have to be considered hacks.
The Basic configuration gives you four presets, the only 100% fail-safe solution is to select the Anonymous option. This disables user tracking but it doesn't interfere with other plugins you may have.
Considering the complexity of the script, before filing a negative feedback, please drop a support request or a bug report. It's the only way for me to enhance this software. Thanks!
