The clearest difference is rating: Security Camera App at 4.3 against Smart Purifier's 1.0. Security Camera App also leads on ratings volume (2.4K vs 1) and review sentiment (21% vs 0%). Smart Purifier's advantage is in-app purchases (none vs 4) and update cadence (fortnightly vs every 3 months). On price, ads and device support there is nothing between them.
