Its good

Great app for speeding through ebooks. You can really customize this app to your preferences - fonts, spacing, background, speed, how many words appear at once, everything. This was great for figuring out which combination of settings works best for me - and it didnt take very long to figure out cause the settings are easy to change.
Things I wish it had are Instapaper integration and Safaris Reading List integration.
Ive really put calibre to good use converting books to ePub and putting the calibre library on Dropbox makes getting my books into Velocireader effortless.
