How it works

PDFs are made for paper. On a phone that means pinching, zooming and scrolling sideways to follow one sentence across two narrow columns. Uncrease reads the PDF and turns it back into text that flows to fit your screen: headings, paragraphs, lists and footnotes, with figures and tables kept where they belong.

Open a PDF or EPUB from Files, share a link from your browser, or find something new in Discover: public-domain classics from Project Gutenberg, research papers from arXiv and open-access books from OAPEN. Recommendations come from what you read, worked out on your phone.

Read by scrolling or by turning pages, look up a footnote without losing your place, and have any book read aloud while you walk.

Your size, your theme

Text size, font, spacing and width, with light, sepia, dark and true black themes.

Figures stay in place

Pictures, tables and equations appear where they belong. Tap one to zoom in.

Scanned pages too

Pages that are only pictures of text are read on the phone and turned into text.

Highlight, search, listen

Highlights and notes, search across your library, and read aloud with the screen off.

Free books and papers

Search Project Gutenberg, arXiv and OAPEN, or add your own OPDS catalog.

Stays on your phone

No account. Your library, highlights and reading never leave your device.
