Verdict

The call

The clearest difference is review sentiment: Blue Sketch at 77% against Draft Paper's 51%. Blue Sketch also leads on rating (4.7 vs 4.4). Draft Paper's advantage is ratings volume (16K vs 327) and update cadence (every 2 weeks vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
