Verdict
The clearest difference is ads: Flow Smart v2 at none against Air Quality index's shown. Flow Smart v2 also leads on iOS requirement (11.0 vs 15.0). Air Quality index's advantage is update cadence (fortnightly vs monthly). On price, in-app purchases and device support there is nothing between them.
