Verdict
The clearest difference is rating: OxyKnight at 4.0 against Beyond Oximeter's 2.2. OxyKnight also leads on review sentiment (50% vs 13%) and update cadence (fortnightly vs every 3 months). Beyond Oximeter's advantage is ratings volume (90 vs 12) and iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and monetization model there is nothing between them.
