Good idea, poor execution.
Im in Portland, OR, and there are two (sometimes three) *giant* mountains visible. There are also a couple dozen "hills".
This app shows all the close-in hills that no one knows or cares about, but completely ignores the huge, distant mountains.
The peaks listed should be prioritized by apparent size, not by distance. And the distance should extend to at least 100KM, the usual limits of visibility.
