Readrrr uses Rapid Serial Visual Presentation to show words one at a time in the same spot, and a natural voice can read each word aloud as it appears. Your eyes don't have to jump across lines, so you don't lose your place and read faster. Seeing and hearing every word at the same time also keeps your mind from drifting. Start at your normal pace and speed up as it gets comfortable. A Readrrr subscription or one-time purchase includes everything below: RSVP READER Every word has one letter marked in red for your eyes to rest on, so you never have to look for where the word starts. You can change the speed at any time. NARRATION Pick a voice and it reads along in sync with every word at any speed. The voice runs on your phone, so it works offline. SHORT READS Non-fiction you can finish in 10 to 20 minutes, on topics like history, health, science and economics. Each one is written to be read in Readrrr and sits in a collection with related reads. New ones come out every week, and you can suggest a topic. READ ANYTHING Import PDFs and EPUBs, send an article from Safari with one tap, paste text, or scan pages from a paper book. APP LOCKING Pick the apps that take up your day. Starting at 4 am they stay locked until you've read your daily word goal. Every day you hit it adds to your streak. If you really need one of them, you can unlock for 10 minutes once a day. HIGHLIGHTS Save any passage while you read. Readrrr sorts your highlights into themes and brings old ones back to you in the app and in a Home Screen widget, so you don't forget what you read. STATS Track your reading speed, words read and streak as they grow. SYNC Your library, reading position and stats stay in sync across your devices. SUBSCRIPTION Readrrr requires a subscription or a one-time purchase. Subscriptions renew automatically unless you cancel at least 24 hours before the current period ends. You can manage them in your App Store account settings. Privacy Policy: https://www.ocule.no/readrrr/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
