Verdict
The clearest difference is rating: ArrayCalc Viewer at 4.1 against Q's 3.0. ArrayCalc Viewer also leads on review sentiment (50% vs 13%) and monetization model (free vs free with in-app purchases). Q's advantage is ratings volume (53 vs 8) and iOS requirement (12.0 vs 16). On price, update cadence, ads and in-app purchases there is nothing between them.
