You can also reduce line transition errors by increasing font size and line spacing. The font in the "What is it" paragraph is, to my eyes, too small and tightly spaced to be easily readable (perhaps purposefully, to demonstrate their value).
That's probably the point: Beeline makes it easier to read more text on a small screen. Increasing font size and line spacing doesn't work well on a smartphone, much less a smartwatch.
It works fine, it just creates a bit more scrolling.
I think the line spacing and line length matter more than the font size. With these high-resolution displays, the fonts can be pretty small, and they're still readable, but you then need to make the column narrower and add a couple pixels to the line height.
Completely agree. I couldn't make sense of the gradient deal, but open up the inspector, set the body font size to 16px and the paragraph line height to 150% and it all becomes a lot clearer.
