Google Docs vs Microsoft Word: Which Wins on Android for Real Work

Both apps are free to open on a phone, so that is not the real question. The real question is which one behaves better on Android when you are actually working: co-editing a document with three other people, picking up an edit mid-commute with no signal, or opening a file someone built in the other app. On Google Play, Microsoft Word carries a 4.8-star rating across 16.93 million ratings, while Google Docs sits at a 4.7-star rating across 2.70 million ratings. Both numbers describe two mature, widely trusted apps, not a lopsided contest.

This comparison stays on the two mainstream cloud suites as Android apps, not on open-source alternatives or file-format internals. If offline-first, open-source office software is what you are actually weighing, our OnlyOffice vs LibreOffice comparison covers that ground already. Here, the axes are collaboration workflow, offline editing on a phone, formatting fidelity between the two, and cost.

Three problems show up fast once either app leaves the desktop. A comment thread built for a laptop screen turns cramped and hard to reply to on a 6-inch display. A document edited on Word's desktop app can hit a wall on mobile that has nothing to do with your subscription tier and everything to do with your screen size. And a file built with heavy formatting in one app can shift tables, spacing, or tracked changes the moment it opens in the other.

The Real Challenges of Choosing an Android Office App

• Collaboration that stalls on a phone. Following a thread of comments or suggested edits is harder on a small screen, and a workflow built around a laptop rarely translates cleanly.
• A screen-size wall you never expected. Word's mobile editing is capped by device size, not just by subscription tier, and most comparisons never mention it.
• Documents that look different when they cross over. A DOCX built with dense formatting in Word can shift once it passes through Docs' conversion layer, and vice versa.
• Storage that fills up quietly. Google's free 15 GB is shared across Drive, Gmail, Photos, and WhatsApp backups, so a phone full of photos can crowd out document storage without warning.
• Confusing "free to open" with "free to fully use." Both apps are free to install, but the feature set behind that free tier is not identical on either side.

Quick Comparison

Here is how Google Docs and Microsoft Word compare as Android apps, before the section-by-section breakdown below.

Real-Time Collaboration and Comments on Android

Google Docs was built around live, simultaneous editing from the start, and that shows most clearly in how comments work on Android. Per Google's own support page, you can add, edit, reply to, and delete comments, assign tasks to a specific person by typing "@" and their name, and react to comments or content with emoji, all from the phone app. Suggesting mode works the same way: per Google's documentation, changes appear in a distinct color and deletions show as strikethrough, so a collaborator can propose an edit without touching the underlying text.

Word takes a more structured, desktop-first approach to feedback. Microsoft's own support page on giving and receiving feedback in Word lists two separate tools: Track Changes for direct edits to the text, and comments for questions or corrections that do not touch the text itself. It also notes that review behavior differs by platform, Word for desktop or iOS requires turning Track Changes on separately, while Word for the web handles review through its own mode. Reviewing and adding comments in the browser or web app is documented on Microsoft's comments support page, but that page has no mention of the mobile app specifically, which tells you where Microsoft's own documentation effort has been concentrated.

For a group actively co-writing on phones, that difference is the whole ballgame. Docs treats the phone as a first-class place to comment, assign, and resolve. Word treats the phone as a place to read and make quick edits, with the deeper review workflow living on desktop and web.

The Screen-Size Cap Microsoft Doesn't Advertise

This is the detail most comparisons of these two apps skip entirely, and it is specific to Android and iOS rather than desktop. According to Microsoft's own support documentation, editing in the Microsoft 365 mobile apps is limited by screen size, not just by subscription status. Some qualifying plans allow editing on screens up to 10.9 inches, while all non-qualifying plans, which includes the free tier, are capped at 10.1 inches. Past that size, the app still lets you create and view files and do basic editing, but the fuller editing experience expects a qualifying subscription.

On a typical Android phone, well under either limit, this never comes up. It becomes real the moment someone tries to do serious document work on a larger Android tablet or a foldable opened flat, where the free tier's 10.1-inch ceiling can sit uncomfortably close to the device's actual screen size. Google Docs carries no equivalent device-size restriction on its editing features. If your workflow spans a phone and a large tablet, that asymmetry is worth knowing before you standardize on one app for a whole team.

Offline Editing on a Phone

Google documents its Android offline behavior in detail. Per Google's own support page, you can create, view, and edit Docs, Sheets, and Slides files with no internet connection at all, by turning on "Make recent files available offline" in the app's settings, or by marking a specific file available offline from its menu. Offline files then sit in their own "Offline" section inside the app for quick access.

Word's mobile apps are also built for editing on the go, and Microsoft's own guidance to mobile users centers on the screen-size limit covered above rather than a hard internet requirement for every keystroke. What Microsoft's public documentation does not spell out in the same explicit, step-by-step way is exactly how offline sync behaves across every Android device and file type, so if uninterrupted offline editing is the deciding factor for your workflow, Docs is the better-documented, more predictable choice on Android today.

Formatting Fidelity When a Document Crosses Over

DOCX is Word's native format. Google Docs edits DOCX files by converting them into its own internal format first, then converting back on export. For a document that stays inside one app for its entire life, this rarely matters. For a file that moves back and forth, a dense table, a custom style, or a long tracked-changes history is exactly where a shift is most likely to appear, whether that is a font substitution, a page break landing in a new place, or a comment thread that renders differently once it opens in the other app.

Neither app is "wrong" here, they simply optimize for different starting points. Word optimizes for DOCX as a first-class format. Docs optimizes for real-time collaboration and treats DOCX as something to translate on the way in and out. If a document needs to survive several round trips between a Word-only collaborator and a Docs-only collaborator with zero formatting drift, Word is the safer default, since it never has to convert its own native format.

What Each One Actually Costs

Google Docs itself has no price tag. It comes with any Google account and draws against the same free storage pool as the rest of a Google account. Per Google's own support page, a free account gets 15 GB shared across Google Drive, Gmail, Google Photos, and WhatsApp backups, so a phone with a large photo library can eat into document storage without the owner realizing it. If that 15 GB runs out, Google One's own listed plans start at $1.99 a month for 100 GB, with 2 TB at $9.99 a month and an AI Pro tier at $19.99 a month, per Google One's plans page.

Word's mobile app is also free to install, and Microsoft's own mobile support page confirms non-subscribers can create and view files and do basic editing at no cost. Getting past the basic tier, including the full screen-size allowance on mobile, effectively means Microsoft 365. Per the Microsoft 365 plans and pricing page, Personal runs $9.99 a month or $99.99 a year, Family runs $12.99 a month or $129.99 a year, and Premium runs $19.99 a month or $199.99 a year. A one-time alternative, Office Home 2024, is listed at $179.99 with no subscription. Anyone already paying for Microsoft 365 for Outlook or OneDrive gets full Word mobile access bundled in, which changes the math considerably. Households already juggling a note-taking subscription alongside an office suite may recognize this same free-versus-paid split from our Evernote vs OneNote comparison.

Google Docs: Upsides and Downsides

Upsides:

• No device screen-size limit on editing, unlike Word's mobile tier structure
• Comments, suggestions, task assignment, and emoji reactions all work fully on Android, per Google's own documentation
• Offline editing is documented in detail and works without a paid plan
• Completely free with any Google account, no separate purchase

Downsides:

• DOCX files pass through a conversion layer rather than opening as a native format
• Free storage is shared with Gmail, Photos, and WhatsApp backups, so it can run out fast
• Play Store rating sample is far smaller than Word's, 2.70 million versus 16.93 million ratings

Microsoft Word: Upsides and Downsides

Upsides:

• DOCX is its native format, giving it the edge on formatting fidelity for complex documents
• Track Changes and comments offer a more structured, desktop-grade review workflow
• Free to install with basic editing available at no cost
• Bundled in for anyone already paying for Microsoft 365

Downsides:

• Free-tier mobile editing is capped at 10.1-inch screens, a limit Google Docs does not have
• Full features effectively require a Microsoft 365 subscription starting at $9.99 a month
• Microsoft's own documentation says less about mobile-specific comment and offline behavior than Google's does about Docs

How to Pick Between Google Docs and Microsoft Word on Android

Choose Google Docs if your work is phone-first and collaborative: a small team drafting together, comments and assignments flying back and forth, and editing that needs to keep working with no signal. Its offline behavior is well documented, its collaboration tools work fully on Android, and it carries no device screen-size penalty.

Choose Microsoft Word if the documents themselves are heavy: dense formatting, long tracked-changes histories, or files that need to round-trip with Word-only collaborators without drifting. That fidelity, plus Track Changes as a distinct review layer, is worth the Microsoft 365 subscription for teams that live in complex DOCX files daily.

If a large Android tablet or foldable is part of your setup, weigh the 10.1-inch free-tier cap seriously before committing a whole team to Word's mobile app without checking their plan tier first. That single Android-specific limit, more than any feature list, is where the choice can quietly go wrong.
