The two partners are introducing new tools that make it much easier for public health authorities to implement digital exposure notification, without the need for developing and maintaining their own individual apps. Apple makes this possible via the iOS 13.7 system update, out today, while Google is implementing it with an automatically-generated application on Android 6.0 and up coming later this month, a workaround required because of the very different method through which it manages system services and OS updates. > This change in the way the technology works means that users won’t have to actually download and install a dedicated app created by the public health authority (PHA) in their jurisdiction to participate. Instead, you’ll receive a notification that provides information supplied by your local health authority about the exposure notification system and what it does, from which you can choose to opt-in. On iOS, that’ll mean installing a provisioning profile, while on Android, it’ll result in that auto-generated app, which is installed via the Google Play store. Apple and Google clarified that Exposure Notification Express co-exists with existing dedicated PHA apps, rather than replacing it.
