Verdict
The clearest difference is ratings volume: Whosfan at 990 against 올차트[ALLCHART]'s 29. Whosfan also leads on rating (1.4 vs 1.1). On price, review sentiment, update cadence and ads 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. Whosfan sells 4 one-off in-app purchases and 올차트[ALLCHART] sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Whosfan holds the better App Store score, 1.4 against 1.1. That said, the two scores are not equally well evidenced: Whosfan has 990 ratings behind it against 29, so its average is the more settled of the two. Written reviews point the same way: 4% of Whosfan's written reviews are positive against 3% of 올차트[ALLCHART]'s.
Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on September 19, 2026 and September 24, 2026 respectively.
