Verdict
The clearest difference is rating: Office Attendance at 4.7 against BAT's 3.1. Office Attendance also leads on update cadence (every 2 days vs every 3 weeks). BAT's advantage is review sentiment (24% vs 0%) and ratings volume (76 vs 6). 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.
Office Attendance holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: BAT has 76 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 24% of BAT's written reviews are positive against 0% of Office Attendance's, so the app with the better star average is not the one people write more warmly about.
BAT ships an update every 3 weeks, Office Attendance every 2 days. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
