Add to Home Screen iOS/Android

Add to Home Screen iOS/Android

Can anyone recommend the best method to get users to "Add to Home Screen".  I've built a mobile site with JQM and now want to remind users to add it to their home screen on iOS and Android phones.  Seems like most people don't know this can be done.  I've found this script, and input on using it or is there a better approach for JQM?  Thanks!
