Open anything.
Leaf Viewer is one app for the files on your iPhone and iPad. Open a document, a photo, a song, a film, a ZIP, a 3D model or a map, from the Files app or from any app's Share and Open In, and it is shown the way it was meant to look. Leaf opens more than 1,700 kinds of file, from this year's and from forty years ago, and it never changes any of them.
Documents look like themselves. A Word file shows as its pages, a spreadsheet as its tables and charts, a presentation as its slides, an e-book as a book. Old documents open too: ClarisWorks and AppleWorks, MacWrite, WordPerfect, Works and more, as their pages.
Music and films play, with lyrics and subtitles, including the old formats other players gave up on. Photos fit the screen, pinch to zoom and turn, camera raw and HEIC included.
Look inside archives and disk images without unpacking anything, and open each file where it is.
What it opens:
• Documents, spreadsheets and presentations: Word, Excel, PowerPoint, Pages, Keynote, OpenDocument, Rich Text, WordPerfect, Works, ClarisWorks, MacWrite, PageMaker and more

…and a great many more. If a file you need doesn't open, tell us.
On an iPhone the contents slide in from the side; on an iPad they sit beside the page. It follows your light or dark appearance, and prints with the system's print sheet.
It only reads. It never edits, saves or changes the files it opens, and a file from a stranger is shown, never run. A locked document opens with its password, used once and kept nowhere.
Try every feature free for 14 days. After that, opening files needs the Leaf Viewer licence: one in-app purchase, yours for good, on your iPhone, iPad and Mac alike, with Restore Purchases. Signing in to an Ontiqo account is optional.
No tracking and no advertising, and your files never leave your device.

Choose any accent colour of your own. Saved web pages and Safari web archives show the page. Copied PDF text no longer turns into boxes, and old Word files from DOS and the Mac open.
