I have an Iwatch 6 and wanted to try the sleep app function and there is no sleep app on my Iwatch. I’ve looked everywhere, even the App Store but it’s not available. Is there a reason for this? It’s on my health app, but not the watch itself.
It's automatically installed on the watch in WatchOS7.
And it is available in the watch appstore,search for "Sleep" and it's quite a long way down the list.
