Verdict

The call

The clearest difference is review sentiment: Pet Metronome at 100% against IMSLP's 70%. Pet Metronome also leads on rating (4.8 vs 4.6) and update cadence (every 4 days vs every 10 days). IMSLP's advantage is ratings volume (514 vs 13) and iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.
