# 量化狗 vs K线练习

The clearest difference is ads: 量化狗 at none against K线练习's shown. K线练习's advantage is update cadence (every 2 weeks vs monthly) and iOS requirement (9.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 量化狗 sells 8 in-app purchases, starting at $99.99 per month and K线练习 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

量化狗 ships an update monthly, K线练习 every 2 weeks. The most recent releases landed on October 20, 2026 and October 27, 2026 respectively.
