# K线训练营 vs Quantify.US

The clearest difference is ads: Quantify.US at none against K线训练营's shown. Quantify.US also leads on rating (5.0 vs 4.7). K线训练营's advantage is ratings volume (100 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. K线训练营 sells 12 one-off in-app purchases and Quantify.US sells 7 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Quantify.US holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: K线训练营 has 100 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 5, 2026 and September 20, 2026 respectively.
