Have you ever wanted to read some book, but it felt like it needed too much time and was simply boring? FLOOX will make reading much faster and much more fun (once you get a hang of it ;) It is based on RSVP (Rapid Serial Visual Presentation) method, which has been scientifically proven to increase the reading speed by 33% while retaining the same comprehension level (G. Öquist, M. Goldstein). While most speed-reading techniques require a lot of self-discipline to keep a high speed, FLOOX keeps the speed you choose, so that you can relax and concentrate on the meaning. Reading becomes like watching a movie, while remaining a great exercise for your brain. Since words on the screen are always moving and grabbing your attention, concentrating on reading is also much easier than for a static text, where your mind tends to wonder away because there is no action. The basis of any speed reading is to reduce the vocalization: understand the words without pronouncing them with your internal voice; and FLOOX helps you achieve this. So your regular reading will also improve after using FLOOX! Besides, since you only need to see one word a time, you can use a much larger font and hold the device farther away, which is less tiring on your eyes and saves your vision. Remember: this method requires a skill. You can truly appreciate it only after practicing it for a couple of weeks. + Supports EPUB, MOBI, FB2, PDF, TXT and HTML files, Copy-Paste and Sharing. There are many websites to convert other formats to EPUB or FB2. + When pasting or sharing links, they are loaded automatically, so you can read the news or Wikipedia using FLOOX + See the remaining time to finish the book and the estimated speed (words per minute) + Easily increase/decrease speed or fine-tune all delays to make it behave exactly as you want + See the words surrounding the current words, to roughly understand the context and look ahead or behind when needed + Set colors you like + Right-to-Left support + Chinese and Japanese languages support You can purchase a 1-year AD-FREE subscription!

The call

On price, ads and device support there is nothing between them.
