SumDoc — DOCX Document Editor

Productivity

Free · Designed for iPad. Not verified for macOS.

SumDoc opens and edits Word documents on your device. The editor runs on the same native DOCX engine that powers SumOffice on the desktop and on the server — so a document looks and behaves the same wherever you open it. No re-rendering, no drift between what you see on the phone and what your colleague sees on a laptop. WHAT IT DOES • Opens .docx files from your device • Edits text, applies styles and formatting • Keeps the document structure intact — tables, lists, page layout YOUR FILES STAY YOURS Editing happens on the device. Documents are not uploaded anywhere, and the app does not require an account to open a file. PART OF SUMOFFICE SumOffice is an office suite built around one document engine: the same logic in a desktop application, inside your own product, on a server, and here on the phone. SumSheet is its spreadsheet counterpart. SumOffice is an independent product and is not affiliated with Microsoft. Learn more: https://sumoffice.com

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Open documents from the Files app and other apps: SumDoc now appears in “Open in…” for Word documents, and a document opened this way shows up in Recents with its real name. Report a problem: choose a service level (Premium, Business, Standard) right in the form; the form speaks the language of the app. Fixes and improvements from the desktop build.
