# 睡眠精灵 vs 白噪音

睡眠精灵 and 白噪音 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. 睡眠精灵 sells 3 in-app purchases, starting at $3.49 per month and 白噪音 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

睡眠精灵 ships an update every 5 weeks, 白噪音 every 2 months. Both last shipped on November 3, 2026.
