# One Tasks vs CalendarBridge

The clearest difference is in-app purchases: One Tasks at none against CalendarBridge's 6. One Tasks also leads on ratings volume (273 vs 7) and rating (4.8 vs 4.6). CalendarBridge's advantage is update cadence (weekly vs every 4 weeks) and review sentiment (100% vs 89%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. CalendarBridge sells 6 in-app purchases, starting at $5.00 per month. One Tasks asks for nothing beyond the download.

One Tasks holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: One Tasks has 273 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 89% of One Tasks's written reviews are positive against 100% of CalendarBridge's, so the app with the better star average is not the one people write more warmly about.

One Tasks ships an update every 4 weeks, CalendarBridge weekly. Both last shipped on October 25, 2026.
