Stop scrolling and start reading today, for free, forever. ______________________ Custom EPUB Reader tsundoku uses a custom EPUB renderer optimized for iOS. Read on your phone similar to a book by using paginated mode, allowing you to swipe between pages as though you’re flipping through, or scroll smoothly through your book with continuous scrolling mode. Powerful Japanese Dictionary Other free reading apps don’t have an integrated dictionary. Specialized reading devices are slow, their dictionaries aren’t thorough, and you always have to carry it with you. With tsundoku, you gain access to JMDict, one of the most complete dictionaries around, in addition to Kanji data from the Kanjidic project, and pitch accents from Wadoku, all in your phone. With the tap of a word, you’ll learn everything there is to know about any word. Autosave and progress tracking tsundoku is designed to be on-the-go. That’s why we prioritize automatic progress saving on every book, always. tsundoku will always track your progress, and wait for you where you last left off. Customizable settings tsundoku is designed to be customizable, to suit your needs for any book in any language. Customize font size, line height, font, paginated and continuous scroll modes, and reader theme. With Japanese, gain access to toggleable furigana, and change between vertical and horizontal text direction. ______________________ Check out the official tsundoku webpage: https://www.evansyu.com/projects/tsundoku Changelog: https://www.evansyu.com/projects/tsundoku/changelog Privacy Policy: https://www.evansyu.com/projects/tsundoku/privacy
