# 聊书AI vs K线量化模型

The clearest difference is update cadence: 聊书AI at every 4 days against K线量化模型's fortnightly. 聊书AI also leads on iOS requirement (13.0 vs 18.2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 聊书AI sells 3 in-app purchases, starting at $6.99 per month and K线量化模型 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

聊书AI ships an update every 4 days, K线量化模型 fortnightly. Both last shipped on October 13, 2026.
