# One Tasks vs Week Plan Calendar

The clearest difference is in-app purchases: One Tasks at none against Week Plan Calendar's 1. One Tasks also leads on rating (4.8 vs 4.6) and ratings volume (257 vs 33). Week Plan Calendar's advantage is update cadence (every 2 weeks vs every 4 weeks). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Week Plan Calendar sells 1 in-app purchase, starting at $4.99 per year. 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 33, so its average is the more settled of the two. Written reviews complicate that: 89% of One Tasks's written reviews are positive against 94% of Week Plan Calendar'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, Week Plan Calendar every 2 weeks. The most recent releases landed on September 21, 2026 and September 23, 2026 respectively.
