Verdict

The call

The clearest difference is price: HD at Free against Ensemble Friends's $17.99. HD also leads on rating (5.0 vs 4.0) and ratings volume (3 vs 1). Ensemble Friends's advantage is update cadence (every 4 months vs every 10 months) and iOS requirement (11.0 vs 13.0). On ads, in-app purchases and device support there is nothing between them.
