# 股问 vs Bala量化

The clearest difference is iOS requirement: Bala量化 at 15.0 against 股问's 17.6. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 股问 sells 2 in-app purchases, starting at $4.99 per month and Bala量化 sells 6 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

股问 ships an update weekly, Bala量化 every 5 days. The most recent releases landed on October 31, 2026 and November 9, 2026 respectively.
