My son Jeremy replied Pedometer ++ might work
and I see it on the App Store ?
Jeremy is really great iOS and MacOS programmer by the way. He supervises about 10 programmers working for UMASS Amherst but is living in Colorado. They make socially important apps for police departments to manage clients on the streets and they also make educational apps for incarcerated students. Apple has recruited him but he’s resisted because he wants control over where he lives-his fiancée is in 2nd Med school in Colorado. But apple recently gave them $1,000,000 to create a new version of their incarcerated student app from the ground up that is running in an integrated way on iOS iPad AND MacOS to facilitate teachers creating their own content - previously they created the content.
Here are 3 URLs from about 5 years ago about Jeremy’s work while he was an undergrad at UMass Amherst:
The last is an iCloud link which they say lasts only to 5-13-23.
