About this app

Read into who you'll become.

uSage is an EPUB reader with a built-in dictionary, translation and vocabulary review. Open your own EPUB books, understand unfamiliar words without leaving the page, and revisit saved vocabulary after you read.

Whether you're reading a novel, studying a book or exploring a new subject, keep your books, saved words, highlights and notes together.

READ YOUR OWN EPUB BOOKS
Import EPUB books or open an EPUB file on your phone with uSage. Read your own collection, or choose from the included library of public-domain classics.

UNDERSTAND WORDS IN CONTEXT
Tap a word for its dictionary meaning, part of speech, translation and explanation in the sentence you're reading. Keep following the book without switching to another app.

TRANSLATE PARAGRAPHS
When a passage is difficult to follow, translate the paragraph in place and continue reading.

REVISIT WHAT YOU SAVE
Save unfamiliar words while you read. Practise them in short daily vocabulary reviews using spaced repetition, with the sentence where you found each word.

KEEP HIGHLIGHTS AND NOTES
Highlight passages in four colours, add notes and find your highlights in one place. Save passages to explore later and return to ideas worth keeping.

MAKE READING COMFORTABLE
Choose paged or scrolling reading, light, sepia or dark themes, text size and line spacing. Publisher mode preserves the book's design; Learner mode offers a consistent reading layout.

READ OFFLINE
Download books and dictionaries for offline reading and word lookup. Your reading position, highlights and saved words sync when you're back online.

BUILD A READING HABIT
Track your reading streak, use freeze days for busy weeks and choose optional daily reminders.
