Both are free to download. StepFun sells 13 in-app purchases, starting at $3.99 per month and 纳米AI sells 14 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.3 for StepFun against 4.3 for 纳米AI.
