About Blood Oxygen Level

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.
