Verdict
The clearest difference is rating: StepFun at 4.3 against 秒哒's 3.0. StepFun also leads on ratings volume (8 vs 2). 秒哒's advantage is review sentiment (65% vs 49%). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. StepFun sells 10 in-app purchases, starting at $3.99 per month and 秒哒 sells 7 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
StepFun holds the better App Store score, 4.3 against 3.0. Both are backed by a comparable volume of ratings — 8 and 2 respectively. Written reviews complicate that: 49% of StepFun's written reviews are positive against 65% of 秒哒's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 9 days. The most recent releases landed on November 4, 2026 and November 9, 2026 respectively.
