Verdict

The call

The clearest difference is price: RAVON at Free against Lethe's $0.99. RAVON also leads on rating (4.8 vs 3.8) and ratings volume (84 vs 13). Lethe's advantage is chart position (#58 vs unranked) and update cadence (every 4 weeks vs every 2 months). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
