Verdict

The call

The clearest difference is price: Winix Smart at Free against Day's $0.99. Winix Smart also leads on ratings volume (35K vs 4). Day's advantage is rating (5.0 vs 4.6) and update cadence (every 10 days vs monthly). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
