Verdict
The clearest difference is monetization model: Converso at free against SonLerni's free with in-app purchases. Converso also leads on update cadence (every 2 days vs weekly) and ratings volume (7 vs 2). SonLerni's advantage is rating (5.0 vs 4.7). On price, review sentiment, ads and in-app purchases there is nothing between them.
