# One Calendar vs ChoreStar

The clearest difference is ratings volume: One Calendar at 21K against ChoreStar's 5. ChoreStar's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. One Calendar sells 1 one-off in-app purchase and ChoreStar sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ChoreStar holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: One Calendar has 21K ratings behind it against 5, so its average is the more settled of the two.

One Calendar ships an update fortnightly, ChoreStar every 10 days. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
