# 大有空间 vs 洞天艺术

大有空间 and 洞天艺术 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. 大有空间 sells 10 one-off in-app purchases and 洞天艺术 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

大有空间 ships an update every 3 weeks, 洞天艺术 fortnightly. The most recent releases landed on October 7, 2026 and October 11, 2026 respectively.
