# Day2U vs Day

The clearest difference is ads: Day at none against Day2U's shown. Day also leads on update cadence (every 3 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Day2U sells 1 one-off in-app purchase and Day sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Day2U ships an update fortnightly, Day every 3 days. The most recent releases landed on October 5, 2026 and October 7, 2026 respectively.
