Zensorium, a Singapore-based startup was showing off at CES in Las Vegas its iPhone pulse oximeter called Tinké, that provides continuous blood oxygen level monitoring. Along with measuring oxygen levels, Tinké also tracks the heart rate, respiratory rate, and heart rate variability. The device, which weighs .4 oz (10.7g), works with a companion iOS app that displays the different cardiac metrics measured. The app displays a Vita index that is a fitness score computed from the user’s heart rate, blood oxygen level and respiratory rate. The app also displays a Zen score based on the heart rate variability data, and is a supposed measure of the user’s state of relaxation.
In order to use the Tinké , it is first connected to the dock connector of the iPhone. The user needs to wait untill a red light appears on the device, after which the user is required to place his or her thumb over the two holes on top of the unit and the reading is taken. The iOS app automatically registers and tracks daily readings and helps users track their cardiac metrics over an extended time.
The device can now be ordered for iOS devices for $83.30 and will soon be available for Android devices as well.
