”People do use Add to Home Screen… Recently we were testing some prototypes on iOS… Of the 10 people we talked to, 4 were familiar with this flow and had saved various things this way.

It tells us that it’s something that at least some regular people do and that it’s not a hidden power user feature… it’s a good reminder to check your assumptions.”
