# Black Keys vs QR code

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.

Black Keys costs $0.99 and QR code $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

QR code holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: Black Keys has 27 ratings behind it against 1, so its average is the more settled of the two.

Black Keys ships an update fortnightly, QR code every 6 days. Both last shipped on October 10, 2026.
