Verdict

The call

The clearest difference is rating: QR Code at 5.0 against Calculator Pro's 4.4. QR Code also leads on update cadence (every 4 days vs every 2 weeks) and device support (3 vs 1). Calculator Pro's advantage is ratings volume (62 vs 9). On price, ads, in-app purchases and monetization model there is nothing between them.
