Like @marcoarment, I am interested in apps that can find patterns in my behavior and make useful observations.
For example, I learned that as long as I watch a lot of YouTube and stay out of southwest Massachusetts, I get more steps.
This is called data science.
Unrelated: I had to hunt a little to find those screenshots, and, as usual, I also found some other pretty good old stuff.
I love finding pretty good old stuff.
I love that the ad writers had the audacity to put “Do not ramble, though” in two full text-laden pages.
