Words that carry a footnote in the Church's edition of the scriptures are shown in light blue, just like a printed set, so you can see where there is more to learn and go straight to it.
How to use it
Read any chapter, or open a study. Words in light blue have footnotes.
Tap a light blue word to open that verse's footnotes on ChurchofJesusChrist.org.
Or tap the pencil on a verse, open Explore, and tap Footnotes; the number beside it tells you how many that verse has.
Good to know
The footnotes themselves live on the Church's site, so opening them needs a connection. The blue words show offline.
You can still start a highlight on a blue word: press and drag to select, and nothing opens.
The same Explore menu also shows how many talks, songs and articles cite the verse.
