SumDoc

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

Verdict
The clearest difference is in-app purchases: SumDoc at none against PDF Maker & Reader's 2. SumDoc also leads on ads (none vs shown) and update cadence (every 5 days vs every 2 months). PDF Maker & Reader's advantage is iOS requirement (13.0 vs 16.0). On price and device support there is nothing between them.
