Verdict

The call

The clearest difference is rating: QR code at 5.0 against Black Keys's 3.4. QR code also leads on update cadence (every 6 days vs fortnightly). Black Keys's advantage is monetization model (free vs paid) and ratings volume (27 vs 1). On price, ads, in-app purchases and device support there is nothing between them.
