I am not sure what to think about this.

This is both a thrilling prospect and a frustrating one. The sound is linked to the line of text for which it was composed, and as I begin reading a Sherlock Holmes mystery on my iPhone, an arrow in the right-hand margin slides down before my eyes can follow. I tap on the arrow, which is supposed to adjust the music to my reading pace, but from time to time it skips and the sound switches suddenly from a synth to a doorbell. If I turn back a page, it’s like rewinding to an earlier spot on a record track.
