Verdict

The call

The clearest difference is rating: Z1 Air at 5.0 against REALLY's 4.3. Z1 Air also leads on review sentiment (100% vs 88%) and iOS requirement (15.0 vs 17.0). REALLY's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (18 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
