In my opinion this experiment is missing a key element of designing for UI density: typography. These screens use a fixed-width font at a single size. It’s a retro 1980 text-mode UI look, and it’s fine if that was the design constraint they wanted. But you can squeeze a lot more information on screen if you can have a proper hierarchy of typefaces and sizes. (As a basic example, the “About” box now consumes almost a quarter of the screen on a phone. A change to a smaller proportional font could fit this information in half the space and still remain readable on a phone.) If you look at the works of an accomplished information designer like Edward Tufte, he often obsesses about getting the typography right. His books use many typographic elements and scales even for the body text, outside of the visualizations.
