Taking a measurement is easy. It's what you do with the measurement that is important. You can use the iHealth Air pulse oximeter like a conventional (offline) oximeter, but when you connect and synchronize your data with the free iHealth MyVitals app you can track, record, manage and share your results with your family or your doctor. Just download the iHealth MyVitals app on the App Store or Google Play and start monitoring your health.
Your iHealth account also gives you free access to a secure cloud space, so you can manage your data, track your trends and share your data. To do this, go to your secure cloud space and sign in to the same account that you use to sign in to the iHealth MyVitals app.
