# Fastyn vs 轻动健康

Fastyn and 轻动健康 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. Fastyn sells 3 in-app purchases, starting at $1.99 per 7 days and 轻动健康 sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
