Verdict

The call

The clearest difference is ads: Microsoft Word at none against AO Office's shown. Microsoft Word also leads on rating (4.7 vs 4.3) and ratings volume (3M vs 1.5K). AO Office's advantage is iOS requirement (13 vs 18.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Microsoft Word sells 12 in-app purchases, starting at $5.99 per month and AO Office sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Microsoft Word holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Microsoft Word has 3M ratings behind it against 1.5K, so its average is the more settled of the two. Written reviews complicate that: 37% of Microsoft Word's written reviews are positive against 39% of AO Office's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Microsoft Word ships an update weekly, AO Office every 5 weeks. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
