Verdict
The clearest difference is update cadence: Blueair at every 3 weeks against GreenTech Connect's every 16 months. Blueair also leads on review sentiment (26% vs 0%) and ratings volume (24K vs 13). GreenTech Connect's advantage is iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
