When I was in university, for my Android course I implemented a speedreading app that worked by a) identifying a pivot character in the word and b) showing each word in the same spot of the screen, with the pivot of the word centered (as opposed to normal center justification), at a rate that the user could increase to their comfort.

Over the course of researching the specific algorithm we were using, I learned about eye saccades and speedreading theory. Even untrained users of the app could break 400 WPM comfortably using our test data, and regular users on our team were able to comfortably maintain over 700 WPM without previous training in speedreading.

The big takeaway for me, which actually improved my reading speed for physical texts, was the thing that slows you down the most when reading is eye movements. If you can will your eyes to move over lines faster, you can read faster. YMMV depending on the nature of the text (deeply technical stuff with unfamiliar words is gonna take more time to read thru, a big weakness of the automated speedreading app) but if you make a habit of trying to read faster, you'll find you improve over time.
