Verdict
The clearest difference is in-app purchases: Roll Calculator at none against QR Code's 7. Roll Calculator also leads on iOS requirement (12.0 vs 14.0). QR Code's advantage is review sentiment (33% vs 0%) and ratings volume (13K vs 11). On price, update cadence, ads and device support there is nothing between them.
