# 알라딘 vs 사락

The clearest difference is rating: 사락 at 4.0 against 알라딘's 2.5. 사락 also leads on in-app purchases (none vs 7). 알라딘's advantage is ratings volume (29 vs 3). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. 알라딘 sells 7 one-off in-app purchases. 사락 asks for nothing beyond the download.

사락 holds the better App Store score, 4.0 against 2.5. That said, the two scores are not equally well evidenced: 알라딘 has 29 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 47% of 알라딘's written reviews are positive against 45% of 사락'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 2 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
