# BackOffice X vs O

The clearest difference is rating: BackOffice X at 4.8 against O's 3.7. BackOffice X also leads on device support (3 vs 1). O's advantage is update cadence (every 6 days vs every 2 months) and review sentiment (100% vs 89%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

BackOffice X holds the better App Store score, 4.8 against 3.7. Both are backed by a comparable volume of ratings — 5 and 7 respectively. Written reviews complicate that: 89% of BackOffice X's written reviews are positive against 100% of O's, so the app with the better star average is not the one people write more warmly about.

BackOffice X ships an update every 2 months, O every 6 days. Both last shipped on October 24, 2026.
