I noticed last week that ReadQuick was getting a lot of buzz, thanks to getting Fireballed. But the app is only available for iPad—which IMO is kind of silly for an app that presents one word at a time so you can up your reading speed to 800 WPM or better.

I’ve been using iReadFast for this for months, available for both Mac and iOS, iPhone included. It doesn’t have the very nifty ReadQuick feature that integrates directly with Instapaper, but on both platforms you can copy and paste the text into iReadFast to get the same effect.

iReadFast tip: start at the slowest speed available, then gradually bump it up as you get into a reading session. I typically can comfortably read 800-850 WPM, but I always have to start it in the 450 zone to warm up. My reading comprehension drops like a stone when I try to put more than one word on screen at a time, but your mileage my vary.
