Read faster. Without effort nor any special training. Sounds like a dream? It’s not, thanks to science: the approach we use has been tested by neuro-scientists and proved effective over a wide range of studies. We made it available on iOS and iPadOS with a sleek design and some nice advanced features that will make it a pleasure to use. With UpRead you will be able to: - Read faster, in a matter of minutes. No kidding - Reduce reading effort so that you can read longer - Read articles from the web, imported from Safari or other apps - Read PDF files and other text documents - Save your content and read it later, offline - Customise the reading experience by setting speed, font and color. You’ll be much more effective, process more information and save time. Your professional and personal life will both have a nice boost from using just one little app. There’s no price for this. Since we’re sure you’ll love the app, you can try UpRead for free for a limited time. If you’re still (slowly) reading this, it’s time to press that GET button and start the download. Try the app, it’s worth more than a thousand words. Here’s a few reviews about us: > Magnifique application qui accélère la lecture tout en améliorant l'attention. Indispensable. — Manitoo, Switzerland, Sep 2019 > This app is the one thing I never knew I needed so desperately. […] For my fellow columnist hounds, UpRead is absolutely essential. — dfe1998, USA, Sep 2019 > I have used every flash reader I could Get my hands on. […] The back end works somehow where the others fail. [… ] You will surprise yourself by how fast you can go over time. Now friends who see me reading something look at how fast the words go and tell me that they just see flashing gobbledygook. I thought the same thing but the learning curve is painless! […] Thank you to the UpRead team!!! Finally! An app worthy of my bottom bar! — eightyanthony, USA, Aug 2019 > It's not a free app but it's worth your money! Simple to use very intuitive, I am reading more than ever! Highly recommended. — dhernz1, Honduras, Jul 2019 We’re really happy to receive feedback from our users.
