Verdict

The call

The clearest difference is rating: AO Office at 4.3 against Collabora Office's 3.3. AO Office also leads on ratings volume (1.5K vs 129) and device support (4 vs 2). Collabora Office's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, review sentiment and update cadence there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

AO Office holds the better App Store score, 4.3 against 3.3. That said, the two scores are not equally well evidenced: AO Office has 1.5K ratings behind it against 129, so its average is the more settled of the two. Written reviews complicate that: 39% of AO Office's written reviews are positive against 41% of Collabora Office's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AO Office ships an update every 5 weeks, Collabora Office every 6 weeks. The most recent releases landed on October 26, 2026 and October 27, 2026 respectively.
