# StepFun vs 语鲸

The clearest difference is rating: 语鲸 at 4.8 against StepFun's 4.3. 语鲸 also leads on review sentiment (80% vs 50%) and monetization model (free vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. StepFun sells 13 in-app purchases, starting at $3.99 per month and 语鲸 sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

语鲸 holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: 语鲸 has 50 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 50% of StepFun's written reviews are positive against 80% of 语鲸's.

StepFun ships an update every 9 days, 语鲸 every 6 days. Both last shipped on October 24, 2026.
