The iOX is a smartphone pulse oximeter compatible with Android and iPhone devices from Safe Heart.   The iOX's power is drawn through a headphone jack or USB cable that accompanies each iOX unit and is thus battery-free, saving money and the hassle of replacing batteries that are typical in standard oximeters.   The device is plug and play, and requires simply downloading the iOX application (available on iOS and Android devices) and hitting Start.  In addition to reading the user's blood oxygen saturation levels, the iOX is capable of reading a user's heart rate, perfusion index and respiration rate, and can be used for continuous monitoring so long as the phone has power.  To achieve this, the iOximeter uses an innovative circuit design to send and receive data at a bit-rate that is sufficient for sending the measured telemetry while keeping the power consumption to a minimum.


All iOS devices (iPhone, iPad, iPad Air, iPad Mini models)

All Android handsets and devices that support the USB OTG standard.  Please verify your phone's compatibility with OTG.
