Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. LingoDeer sells 17 in-app purchases, starting at $12.99 per month. 아주대학교 중앙도서관 asks for nothing beyond the download.
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.
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.
