The clearest difference is review sentiment: LingoDeer at 77% against CMU MOBILE's 14%. LingoDeer also leads on rating (4.7 vs 3.0) and ratings volume (28K vs 2). CMU MOBILE's advantage is in-app purchases (none vs 18) and iOS requirement (13.4 vs 15.0). On price, update cadence, ads and device support there is nothing between them.
