# 1Office vs Fast Business

The clearest difference is rating: 1Office at 2.7 against Fast Business's 1.0. 1Office also leads on review sentiment (33% vs 22%) and ratings volume (17 vs 3). Fast Business's advantage is update cadence (fortnightly vs every 5 weeks) and iOS requirement (10.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

1Office holds the better App Store score, 2.7 against 1.0. That said, the two scores are not equally well evidenced: 1Office has 17 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 33% of 1Office's written reviews are positive against 22% of Fast Business's.

1Office ships an update every 5 weeks, Fast Business fortnightly. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
