# 语境岛 vs Rakuo

The clearest difference is update cadence: 语境岛 at every 6 days against Rakuo's fortnightly. 语境岛 also leads on iOS requirement (16.0 vs 18.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 语境岛 sells 6 in-app purchases, starting at $69.99 per year and Rakuo sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

语境岛 ships an update every 6 days, Rakuo fortnightly. Both last shipped on November 9, 2026.
