Does it serve mostly Rob ter Horst, to get a lot of views on his YouTube channel, and to make a lot of money out of advertising revenues from YouTube?

But we do not know of any application which allows easy data processing and offers numerical data analysis where a Apple watch Ultra would be helpful. Choose a 3 lead ECG devce and Python instead, and help us make the software more user friendly.
