# 나이스학부모서비스 vs DYB Window

DYB Window also leads on update cadence (fortnightly vs every 3 months) and ratings volume (20 vs 1). 나이스학부모서비스's advantage is rating (5.0 vs 3.3) and iOS requirement (14.5 vs 16.6).

나이스학부모서비스 holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: DYB Window has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 5% of 나이스학부모서비스's written reviews are positive against 49% of DYB Window's, so the app with the better star average is not the one people write more warmly about.
