# AO Office vs OpenDocument Reader

The clearest difference is in-app purchases: OpenDocument Reader at none against AO Office's 1. OpenDocument Reader also leads on rating (4.5 vs 4.3). AO Office's advantage is review sentiment (39% vs 30%) and iOS requirement (13 vs 15.0). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. AO Office sells 1 one-off in-app purchase. OpenDocument Reader asks for nothing beyond the download.

OpenDocument Reader holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 1.5K and 902 respectively. Written reviews complicate that: 39% of AO Office's written reviews are positive against 30% of OpenDocument Reader's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on September 30, 2026 and September 27, 2026 respectively.
