# 핏데이 vs 사운드짐

The clearest difference is rating: 사운드짐 at 4.7 against 핏데이's 3.3. 사운드짐 also leads on ads (none vs shown). 핏데이's advantage is in-app purchases (none vs 7) and review sentiment (95% vs 82%). On price, ratings volume, update cadence and device support there is nothing between them.

Both are free to download. 사운드짐 sells 6 in-app purchases, starting at $7.99 per month. 핏데이 asks for nothing beyond the download.

사운드짐 holds the better App Store score, 4.7 against 3.3. Both are backed by a comparable volume of ratings — 21 and 19 respectively. Written reviews complicate that: 95% of 핏데이's written reviews are positive against 82% of 사운드짐's, so the app with the better star average is not the one people write more warmly about.

핏데이 ships an update every 2 weeks, 사운드짐 every 3 weeks. Both last shipped on November 2, 2026.
