Verdict

The call

The clearest difference is rating: QMC App at 5.0 against CO's 4.5. QMC App also leads on ads (none vs shown) and monetization model (free vs ad-supported). CO's advantage is ratings volume (1.2K vs 1) and update cadence (fortnightly vs monthly). On price, in-app purchases and device support there is nothing between them.
