Verdict
The clearest difference is price: Traycer at Free against MermaidEditor's $3.99. Traycer also leads on rating (5.0 vs 2.3) and update cadence (every 2 days vs every 3 weeks). MermaidEditor's advantage is ratings volume (10 vs 1). On ads, in-app purchases, chart position and device support there is nothing between them.
