Ok, so even though you didn't program it, clearly it still took a lot of time and effort to create. But what did it do?
I didn't know about those "basement" and "other" locations. Sounds like their specific purpose is to stop an app from being found from the search box until they're fully satisfied with it.
It's so easy to take an app for granted. It's just an icon that's activated with a single tap, does something (hopefully) useful and is then swiped away without another thought. We don't think of the blood, sweat and tears that often went into it and we're never told either, but every developer will know.
