# Focuz vs SleepStack

Focuz and SleepStack are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Focuz sells 1 one-off in-app purchase and SleepStack sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Focuz ships an update weekly, SleepStack every 10 days. The most recent releases landed on October 5, 2026 and October 3, 2026 respectively.
