# Sunday vs WeekOn

The clearest difference is update cadence: WeekOn at every 3 days against Sunday's every 9 days. Sunday's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Sunday sells 1 one-off in-app purchase and WeekOn sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Sunday ships an update every 9 days, WeekOn every 3 days. The most recent releases landed on October 17, 2026 and October 3, 2026 respectively.
