Verdict

The call

The clearest difference is review sentiment: LingoDeer at 77% against 아주대학교 중앙도서관's 11%. LingoDeer also leads on ratings volume (28K vs 1) and update cadence (every 3 weeks vs every 2 months). 아주대학교 중앙도서관's advantage is in-app purchases (none vs 18) and rating (5.0 vs 4.7). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

아주대학교 중앙도서관 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: LingoDeer has 28K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 77% of LingoDeer's written reviews are positive against 11% of 아주대학교 중앙도서관's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

LingoDeer ships an update every 3 weeks, 아주대학교 중앙도서관 every 2 months. The most recent releases landed on September 25, 2026 and June 11, 2026 respectively.
