# 小睡眠 vs 声昔

The clearest difference is rating: 小睡眠 at 4.7 against 声昔's 3.7. 小睡眠 also leads on ratings volume (642 vs 10) and device support (4 vs 2). 声昔's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. 小睡眠 sells 24 in-app purchases, starting at $0.99 per month and 声昔 sells 29 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

小睡眠 holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: 小睡眠 has 642 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 75% of 小睡眠's written reviews are positive against 69% of 声昔's.

小睡眠 ships an update every 2 weeks, 声昔 every 9 days. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
