Wait for the App and subscription plan......
LOL!
I bought one of those cheap Apple iWatch knockoffs that not only tells tome mut monitors heart rate, O2 blood level, distance walked or run, steps, calories and all that stuff.
The ‘app’ that collects all the data and makes charts and graphs was free............for the first month........a but $20 per month after that.
I deleted it.
The data functions I can chart on a Microsoft Excel Spreadsheet for nothing...............
