Turn pages with a blink: right eye for the next page, left eye for the previous one. You don't have to move your hands or change your grip on the phone, which is handy when you read lying down. Works on iPhones with Face ID (TrueDepth camera). I read a lot on my phone. At some point I noticed that the good old reader apps were gone from the App Store, and the new ones were either full of ads, missing something I needed, or painfully slow. So I wrote my own, with the features I wanted and no ads. I use it every day. Features: • Page turning by blinking, hands-free • FB2 and ePub, including zipped files • Large books open quickly: the book is loaded in parts • Font and text layout settings. Changes apply quickly because pages are built on the fly • Paged reading or scrolling • Several page-turn animations • Ready-made themes, or your own • Landscape mode • List of recent books • No ads Supported formats: .fb2, .fb2.zip, .epub, .epub.zip
