Verdict

The call

The clearest difference is review sentiment: Lyn at 100% against Studley's 50%. Lyn also leads on rating (5.0 vs 4.7). Studley's advantage is ratings volume (4.6K vs 2) and update cadence (weekly vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
