We have released an WearOS version of the APT DC app
It shows the Deep Sky Darkness and Narrow Band time for the current night and the current location for easy checkup. As usual it is completely free, without ads, tracking and etc.
Here is a link to the APT apps (Android, iOS, WearOS) page where to find links and QR codes:
