# 上下求索 vs ChatGPro

The clearest difference is ads: 上下求索 at none against ChatGPro's shown. ChatGPro's advantage is update cadence (monthly vs every 2 months) and iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 上下求索 sells 5 in-app purchases, starting at $3.99 per month and ChatGPro sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

上下求索 ships an update every 2 months, ChatGPro monthly. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
