Instead of having to wear a device, users simply pull out Tinké and place their fingertip over the sensor. From this reading, Tinké detects heart rate, respiratory rate (number of breaths per minute), blood oxygen level, and heart rate variability.
The app provides two data points. One is the Vita index, which measures fitness levels by combining heart rate, respiratory rate, and blood oxygen saturation. Your Vita Index number represents your fitness level score out of 99 (how effectively oxygen is being supplied to your muscles.)
The other data point is the zen index, which uses your heart rate variability data to indicate your level of stress and relaxation.
Tinké plugs in right into the phone itself, so it does not have a battery that needs to be recharged.
