■ About ConTenDo
Founded in 2011, ConTenDo is an e-book store.

We also feature independently published books, so you might find something unexpected!

Extensive Selection: Find your favorite books from a wide range of genres, from professional books for business, qualifications, and examinations to magazines and comics.
Creator Support: We provide a service that allows publishers and authors to easily sell e-books, supporting new business opportunities for creators.
Multiple Viewing Methods: We support viewing via dedicated viewers for PCs and mobile devices, as well as browser viewing.
Word Surfing: Associative search using a patented search engine. Expand your search without narrowing down your options to suggest new discoveries!
■ App Features
ConTenDoViewer is a viewer app that allows you to view books purchased from ConTenDo anytime, anywhere.
ConTenDoViewer has been significantly enhanced with newly added convenient features, such as TTS (Text-to-Speech) and a customizable "My Bookshelf" function, which were not available in the browser viewer!
Use ConTenDoViewer to help you acquire qualifications and improve your skills!
◇◆Marker Function◆◇ Reflow
This function allows you to highlight selected text and register the text as a memo.
You can select the marker color and assign tags that can be renamed, allowing you to freely categorize them by combining these.
Registered markers can be accessed from the menu and are displayed grouped by tag for easy access.
Use them according to your purpose and content!
◇◆Text-to-Speech Function◆◇ Reflow
This accessibility-conscious function reads aloud the text on the page when played from the TTS menu.
You can also specify a reading point, and it will read from the text near the selected text.
It also supports text with ruby text, so the base text and ruby text will not be read aloud separately. It can be used for learning while doing other things, or for reviewing books you've already read using audio, allowing you to deepen your understanding of the book's content.
◇◆Bookshelf Customization Function◆◇
This function allows you to freely group downloaded books.
Group them by series, collect your favorite books, and customize your bookshelf to create your own personal bookshelf!
◇◆Sideloading◆◇
In addition to books purchased from Contendo, you can also import and view your own PDF and EPUB files in the app.
Paper documents can also be viewed if they are converted to PDF.
◇◆Offline Viewing◆◇ ※1
This function allows you to read downloaded books anytime, even in places without a network connection, such as on the subway or on an airplane.

◯ Text Size, Spacing, and Background Color Change (Reflow)
