Have a new pulse oximeter, but don't have a place to record your measurements? This app allows you to record your pulse and blood oxygen level daily. It's very simple, just record the measurements and check the statistics over time. IMPORTANT: This app does NOT measure blood oxygen or pulse using your iPhone or iPad, and it does NOT connect to any external medical device. It is a manual logbook for recording readings you enter yourself. This app is not a medical device and is not intended for diagnosis or treatment. Always consult a healthcare professional for medical advice.

Verdict
The clearest difference is rating: Blood Oxygen Level at 4.3 against PulseOximeter's 1.8. Blood Oxygen Level also leads on ratings volume (2K vs 23) and review sentiment (23% vs 0%). PulseOximeter's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.
