# 小时差 vs 星言

小时差 and 星言 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. 小时差 sells 6 one-off in-app purchases and 星言 sells 9 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
