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. 사운드짐 sells 6 in-app purchases, starting at $7.99 per month and Yollo sells 2 in-app purchases, starting at $39.99 per year. Whichever you choose, the download price is not the number that matters.
Yollo holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 19 and 15 respectively. Written reviews complicate that: 82% of 사운드짐's written reviews are positive against 74% of Yollo's, so the app with the better star average is not the one people write more warmly about.
사운드짐 ships an update every 3 weeks, Yollo every 4 weeks. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
