# One Day vs Countdown

The clearest difference is update cadence: Countdown at monthly against One Day's every 12 months. One Day's advantage is ratings volume (91 vs 26) and iOS requirement (12.0 vs 16.0). On price, rating, ads and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.7 for One Day against 4.8 for Countdown. Both are backed by a comparable volume of ratings — 91 and 26 respectively.

One Day ships an update every 12 months, Countdown monthly. The most recent releases landed on October 11, 2026 and October 2, 2026 respectively.
