Verdict
The clearest difference is rating: Blood Oxygen App at 4.6 against Oxi tracker's 2.2. Blood Oxygen App also leads on update cadence (every 2 weeks vs every 6 months) and ratings volume (31K vs 62). Oxi tracker's advantage is in-app purchases (none vs 14) and iOS requirement (8.0 vs 15.0). On price, ads and device support there is nothing between them.
