Reading doesnβt need to become another task to optimize. Rousd is a calm reading companion designed to help you make space for books and build a gentler relationship with reading. When youβre ready, begin a quiet session and put your phone down. Rousd keeps track without displaying elapsed time, countdowns, or goals. When you finish, you can see how long you read, choose the book, leave a note, or simply move on. Over time, your Diary becomes a personal record of time spent with books, while The Shelf gives finished books and reflections a home. Rousd doesnβt replace the book in your hands: it helps you return to it. Features: β’ A hidden reading timer that stays out of sight while you read β’ A calm reading ritual designed to reduce distraction β’ Book search and attribution after each session β’ Optional notes and reflections β’ A Diary of past reading sessions β’ A Shelf for finished books and reviews β’ Manual logging for reading completed outside Rousd β’ No account required No streaks. No badges. No pressure to read faster or more. Whether you read one page or one chapter, it still counts. Read without the rush.
