ReceptionRating · Positive reviews · Number of ratings

OpenDocument Reader holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: OpenDocument Reader has 902 ratings behind it against 157, so its average is the more settled of the two. Written reviews complicate that: 51% of ONLYOFFICE Documents'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.

UpkeepUpdate frequency

ONLYOFFICE Documents ships an update every 6 weeks, OpenDocument Reader every 5 weeks. The most recent releases landed on September 28, 2026 and September 27, 2026 respectively.
