Verdict

The call

The clearest difference is ads: Halo app at none against QR Scanner's shown. Halo app also leads on iOS requirement (12.0 vs 16.4). QR Scanner's advantage is update cadence (every 4 weeks vs every 3 months). On price, in-app purchases and device support there is nothing between them.
