Verdict
The clearest difference is update cadence: DOTEC at every 3 weeks against VAPolyMk3's every 7 months. DOTEC also leads on price ($9.99 vs $14.99) and review sentiment (67% vs 50%). VAPolyMk3's advantage is rating (4.5 vs 4.2). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
