The iOximeter and how it works.

The iOximeter is a pulse oximeter for Smart Phones. A pulse oximeter is a device that measures a person’s pulse rate and blood oxygen saturation by shining a light through the person’s skin. The principle of pulse oximetry is well established, and the measured results are important vital signs used throughout the world of medicine, sports, and aviation.

The iOximeter is one of the only wellness products that’s powered entirely by your device’s headphone jack. There’s no charger needed because there’s no battery to charge. Just plug the included headphone cable of your iOximeter into your iPhone or Android phone, and off you go!
