The Zensorium Tinké is a revolutionary device designed to change the face of mobile fitness and wellness. Tinké is an optical sensory device for smartphones that monitors your fitness and wellness with the touch of a finger. The four aspects that Tinké measures are heart rate, respiratory rate, blood oxygen levels, as well as heart rate variability. It works on the basis of detecting changes in skin blood volume and using advanced signal processing technologies, Tinké transforms detected signals into quantitative data.



A blood oxygen level of above 95% is essential for optimum performance in your daily activities. Fitter people have higher blood oxygen saturation levels. Tinké lets you measure the amount of oxygen carried by the red blood cells in your blood, at any given time.


Heart rate refers to the number of heart beats per minute. It is expressed in beats per minute (bpm). An average adult’s heart rate is usually between 60bpm to 80bpm. Resting heart rate is defined as the heart rate taken when you are first awake or when sitting quietly. Monitoring your resting heart rate daily is an important indicator of your fitness.


Ever found yourself feeling short of breath? Well, our respiratory rate may change due to conditions such as when we’re angry or sad. An important indicator of fitness is respiratory rate taken when a person is resting and at minimum stress. When a person is in the above condition, a respiratory range of 10-20 breaths per minute is considered normal.


Unlike a clock, our heart does not beat at a constant rate. The changes in the rate at which our heart beats at is known as Heart Rate Variability (HRV). Our HRV changes throughout the day, depending on the activities we carry out, our mood, and various other factors.

In Tinké, HRV is used as a measure of how well our body can adapt to these changes by analyzing your heart rate and breathing patterns. The better your body is able to adapt to these changes, the higher is the measure of your HRV. Simply said, HRV is used as a basis to monitor your level of relaxation.

During anxiety, our heart rate rises, muscles tense, we perspire more, and our breathing becomes more rapid and shallow. Your measurement of HRV is thus lower. In contrast, if you are relaxed, your measure of HRV will consequently be higher.


To use, simply start the Tinké app, connect Tinké when prompted and place your thumb on the sensing platform of Tinké to start measuring. Just gentle pressure will suffice. Done. We love simple and easy to use fitness and health devices and have a lot of them in our test pipeline.

We will be testing the recently launched Lightning connector version of Tinké in the next few weeks and a full review will be posted here.
