The clearest difference is price: CATmistry at Free against LearnRussianCases's $2.99. CATmistry also leads on update cadence (every 2 weeks vs every 5 weeks) and iOS requirement (13.0 vs 15.1). LearnRussianCases's advantage is rating (4.5 vs 3.0) and ratings volume (23 vs 2). On ads, in-app purchases and device support there is nothing between them.
