Verdict

The call

The clearest difference is update cadence: Duolingo at weekly against Russian Dictionary Pro's every 14 months. Duolingo also leads on ratings volume (5.5M vs 14) and chart position (#1 vs unranked). Russian Dictionary Pro's advantage is iOS requirement (15.6 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
