Reading may seem like a relaxing thing to do, but don't be fooled. It involves a ton of eye movement -- and one app is on a mission to cut that out.
Spritz gets you through War and Peace faster by showing you one word at a time. One difference between Spritz and other speed-reading apps is that Spritz centres words on a common point. The goal is that your brain will never be stimulated to request any eye movement whatsoever. Similar apps that show one word at a time keep the words generally centred on your screen, but don't pay as much attention to where the word should be, given its length or shape.
