# 알라딘 vs 성북u

The clearest difference is rating: 성북u at 3.0 against 알라딘's 2.5. 성북u also leads on in-app purchases (none vs 7) and update cadence (every 3 weeks vs every 2 months). 알라딘's advantage is ratings volume (29 vs 2) and review sentiment (47% vs 33%). On price, ads, device support and iOS requirement there is nothing between them.

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

성북u holds the better App Store score, 3.0 against 2.5. That said, the two scores are not equally well evidenced: 알라딘 has 29 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 47% of 알라딘's written reviews are positive against 33% of 성북u's, so the app with the better star average is not the one people write more warmly about.

알라딘 ships an update every 2 months, 성북u every 3 weeks. The most recent releases landed on September 29, 2026 and September 23, 2026 respectively.
