Verdict
The clearest difference is in-app purchases: One Tasks at none against CalendarBridge's 6. One Tasks also leads on ratings volume (257 vs 7) and rating (4.8 vs 4.6). CalendarBridge's advantage is update cadence (every 6 days 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 257 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 every 6 days. The most recent releases landed on September 21, 2026 and September 6, 2026 respectively.
