What I find curious is that the entire article seems to be framed in responding to the needs of a single user of the app — the author themselves.

Yet the app is published and has a great App Store review score of 4.8 with 170k+ reviews, and same score with 35k+ reviews for the Watch.

How does the author get feedback and respond to other customers? Or is this simply scratching one's own itch demonstrating its usefulness for others once again?
