Verdict

The call

The clearest difference is review sentiment: Quartet 3 at 90% against Sheet Music Reader Halbestunde's 36%. Quartet 3 also leads on rating (4.7 vs 4.3). Sheet Music Reader Halbestunde's advantage is price (Free vs $16.99) and ratings volume (1.5K vs 22). On ads, in-app purchases, monetization model and device support there is nothing between them.
