Frequently asked questions
What people ask us most before trying Leo.
Does Leo include books?
No. Leo is a reader, not a store: you import your own EPUB and PDF files, or bring them from Calibre, and read them at your pace.
Can I read my Kindle books?
Books bought on Kindle are protected (DRM) and can’t be opened outside Amazon. Any DRM-free EPUB or PDF works perfectly: from your Calibre library, Standard Ebooks, Project Gutenberg or any store that sells DRM-free books.
How is Leo different from Kindle or Apple Books?
Leo is also a full ebook reader for your EPUB and PDF books, with the whole text, its images and your own covers. What it adds is RSVP speed reading: one word at a time, always in sync with the full text, at the pace you choose.
Does Leo work on iPhone and iPad?
Yes, on both iPhone and iPad. There’s no Android version for now.
Which languages can I read in?
The app is in English, Spanish and French. You can read books in any language that separates words with spaces: English, Spanish, French, German, Italian, Portuguese and more. Chinese and Japanese aren’t supported yet.
Will I understand what I read?
Yes, at moderate speeds comprehension holds up; at very high speeds it drops for everyone. If you go too fast, slow down or jump back 10 words with one tap.
What is RSVP reading?
It stands for rapid serial visual presentation: words appear one after another in the same spot on screen, so your eyes don’t have to travel along lines.
Can I read my way?
Yes. You choose the speed, from 100 to 1,000 words per minute, how many words you see at once (1 to 3), the theme, the typeface and its size, including dyslexia-friendly fonts like OpenDyslexic and Atkinson Hyperlegible.
When can I download Leo?
Leo is coming to the App Store soon. Join the waitlist and we’ll email you the day it launches.
