Verdict

The call

The clearest difference is in-app purchases: BandScan at none against Opus One's 2. BandScan also leads on rating (5.0 vs 4.7) and update cadence (every 5 days vs every 3 weeks). Opus One's advantage is ratings volume (975 vs 2) and device support (4 vs 2). On price and ads there is nothing between them.
