# V vs 书谱

The clearest difference is update cadence: 书谱 at weekly against V's every 3 weeks. 书谱 also leads on device support (4 vs 1) and iOS requirement (15.0 vs 17.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

V ships an update every 3 weeks, 书谱 weekly. The most recent releases landed on October 27, 2026 and October 28, 2026 respectively.
