# 瓶洞树洞漂流瓶 vs Oxygen

瓶洞树洞漂流瓶 and Oxygen 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. 瓶洞树洞漂流瓶 sells 14 one-off in-app purchases and Oxygen sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
