# 助眠神器 vs Screen Time Control

助眠神器 and Screen Time Control are too close to call on the numbers: across 3 compared parameters — price, in-app purchases and iOS requirement 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. 助眠神器 sells 1 in-app purchase, starting at $2.99 per year and Screen Time Control sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
