About

SumDoc

Features
Read full description

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 and .docm files — from the Files app, mail, or any app’s “Open in…” • Edits text, applies styles and formatting with the familiar ribbon • Edits pictures: wrap, crop, borders and effects • Keeps the document structure intact — tables, lists, page layout • Built-in assistant: ask how to do something and get the steps, in your language • Report a problem in two taps — your report gets a number and a status right in the app 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. Only what you send to support leaves the phone — see the privacy policy. 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
