# 小睡眠 vs Miko

The clearest difference is in-app purchases: Miko at none against 小睡眠's 28. Miko also leads on ads (none vs shown) and review sentiment (97% vs 75%). 小睡眠's advantage is ratings volume (642 vs 11) and device support (4 vs 2). On price, rating, update cadence and iOS requirement there is nothing between them.

Both are free to download. 小睡眠 sells 24 in-app purchases, starting at $0.99 per month. Miko asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for 小睡眠 against 4.6 for Miko.
