# ZenFocus vs Noot

The clearest difference is update cadence: ZenFocus at every 4 days against Noot's every 9 days. ZenFocus also leads on iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ZenFocus sells 4 in-app purchases, starting at $1.99 per month and Noot sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ZenFocus ships an update every 4 days, Noot every 9 days. The most recent releases landed on October 3, 2026 and October 13, 2026 respectively.
