# K线晋级赛 vs iTradeTrainer

The clearest difference is update cadence: iTradeTrainer at every 6 days against K线晋级赛's every 2 months. iTradeTrainer also leads on device support (3 vs 1) and iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. K线晋级赛 sells 1 one-off in-app purchase and iTradeTrainer sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

K线晋级赛 ships an update every 2 months, iTradeTrainer every 6 days. Both last shipped on October 31, 2026.
