Verdict
The clearest difference is rating: OttoPilot at 2.1 against Smart Purifier's 1.0. OttoPilot also leads on ratings volume (36 vs 2) and review sentiment (15% vs 0%). Smart Purifier's advantage is update cadence (fortnightly vs every 5 weeks) and iOS requirement (11.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.
