# StepFun vs 当贝AI

The clearest difference is rating: StepFun at 4.3 against 当贝AI's 3.5. 当贝AI's advantage is review sentiment (87% vs 50%) and in-app purchases (none vs 13). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. StepFun sells 13 in-app purchases, starting at $3.99 per month. 当贝AI asks for nothing beyond the download.

StepFun holds the better App Store score, 4.3 against 3.5. Both are backed by a comparable volume of ratings — 8 and 8 respectively. Written reviews complicate that: 50% of StepFun's written reviews are positive against 87% of 当贝AI's, so the app with the better star average is not the one people write more warmly about.

StepFun ships an update every 9 days, 当贝AI fortnightly. The most recent releases landed on October 14, 2026 and October 12, 2026 respectively.
