# 纵书卡片 vs Skilltree

The clearest difference is ads: 纵书卡片 at none against Skilltree's shown. Skilltree's advantage is update cadence (every 3 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 纵书卡片 sells 1 one-off in-app purchase and Skilltree sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

纵书卡片 ships an update every 2 months, Skilltree every 3 days. The most recent releases landed on October 10, 2026 and October 4, 2026 respectively.
