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
