I wrote a RSVP app in J2ME for my Sony Ericcson T610. I feel like it made sense then, when the whole screen was so small you couldn't reasonably read long form text on it in any other way. Some of my friends used it to read books on their commute on the tiny screens of phones back then. Now that phones and tablets are not much smaller than books anyway, you really have to be invested into the niche idea of speedreading to find it useful and as I understand it, most research shows that although you can increase your reading speed, it comes with a reduction in understanding and retention if you push it too far.
