Verdict

The call

The clearest difference is update cadence: QuickCard AI at every 2 days against Language Reactor's every 3 weeks. QuickCard AI also leads on chart position (#201 vs unranked). Language Reactor's advantage is ratings volume (3.9K vs 22) and rating (4.8 vs 4.5). On price, ads, in-app purchases and monetization model there is nothing between them.
