Good luck. It looks pretty comprehensive, which should benefit a lot of people. I note that unlike everyone else, you say exactly what the IAP's get you. Most say nothing, cause me to search their website, if it exists, and then not really know what the extra money gets me.

Personally, I'm retired and the only activity worth tracking is my piano practice (which I highly recommend to keep one sharp over the years) and that's really up to me, since everything else is "optional" except necessary chores, and outdoor walks, which the watch tracks. (is that a good data source?)

And by the way, I get no previews, either on Firefox, Safari and the AppStore on the mac, and Safari and the App Store on the phone. Only variable is iCloud Private Relay, which is usually very well behaved., and other apps show.

HTH, fellow vet.
