# K线量化模型 vs 纯K训练助手

The clearest difference is ads: K线量化模型 at none against 纯K训练助手's shown. 纯K训练助手's advantage is update cadence (every 3 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. K线量化模型 sells 3 one-off in-app purchases and 纯K训练助手 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

K线量化模型 ships an update fortnightly, 纯K训练助手 every 3 days. Both last shipped on October 28, 2026.
