# AO Office Pro vs OpenDocument Reader

The clearest difference is price: OpenDocument Reader at Free against AO Office Pro's $19.99. OpenDocument Reader also leads on rating (4.5 vs 4.2) and ratings volume (897 vs 164). AO Office Pro's advantage is ads (none vs shown) and review sentiment (51% vs 31%). On update cadence, in-app purchases and device support there is nothing between them.

OpenDocument Reader is free to download; AO Office Pro costs $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.

OpenDocument Reader holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: OpenDocument Reader has 897 ratings behind it against 164, so its average is the more settled of the two. Written reviews complicate that: 51% of AO Office Pro's written reviews are positive against 31% of OpenDocument Reader's, so the app with the better star average is not the one people write more warmly about.

AO Office Pro ships an update every 6 weeks, OpenDocument Reader every 2 months. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
