[1] The app requires a compatible Bluetooth pulse oximeter to perform measurements. Bluetooth pulse oximeters are sold separately. For a complete list of supported devices go to https://www.appinlights.com/pulseoximetry/supported-devices.html

[2] The app supports exporting SpO2, heart rate, perfusion index and respiratory rate to Apple’s Health app. Not all pulse oximeters measure perfusion index and respiratory rate. Please check your device's literature for supported parameters.

**Note: The app can be installed on 3rd Generation and newer iPads, but because the screens of these devices have a 4:3 aspect ratio, as opposed to a 16:9 aspect ratio of compatible devices, the app is not guaranteed to look or function correctly on iPads.
