# 墨境 vs Penguin

The clearest difference is update cadence: Penguin at every 3 days against 墨境's fortnightly. 墨境's advantage is iOS requirement (15.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 墨境 sells 6 one-off in-app purchases and Penguin sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

墨境 ships an update fortnightly, Penguin every 3 days. The most recent releases landed on October 14, 2026 and October 13, 2026 respectively.
