Verdict
The clearest difference is rating: Poly Metronome at 4.3 against iMetronom's 3.7. Poly Metronome also leads on update cadence (every 5 days vs every 13 months) and ratings volume (204 vs 9). iMetronom's advantage is monetization model (free vs freemium) and iOS requirement (9.2 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
