It's small. It's light. Its unique design means you can take it anywhere and monitor your fitness and wellness anytime.

All it takes is a touch of your finger, and it measures your heart rate, respiratory rate, blood oxygen saturation level & heart rate variability.

Heart Rate

Did you know the lower your resting heart rate is, the fitter you are? Tinké lets you accurately measure your number of heart beats per minute, in seconds.

Blood Oxygen Level

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.

Respiratory Rate

Did you know that your fitness is related to your respiratory rate? The lower your respiratory rate at rest, the fitter you are. Tinké lets you measure the number of breaths you take per minute.

Heart Rate Variability

Our heart does not beat at a constant rate, and the changes in the rate at which our heart beats is known as Heart Rate Variability (HRV). Tinké measures for your HRV to give an indication of your level of relaxation.

Heart Rate

Your heart is probably the hardest working organ in your body. Naturally, you will want to know if it's working at an optimal rate.

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.

A low resting heart rate usually indicates better fitness levels.

People who exercise frequently are generally fitter and exhibit lower resting heart rates.

Did you know?

Heart rate reserve is a term used to quantify your range of potential training heart rate intensities. It is the difference between your maximum heart rate and your resting heart rate.

To obtain your maximum heart rate, you can use this formula:
  • Women: 226-your age
  • Men: 220-your age


Blood Oxygen Level

Why is knowing your level of blood oxygen important?

Put simply,our bodies need a constant level of oxygen circulating in the blood to reach cells and tissues.

The saturation of peripheral oxygen (SpO2) is a relative measurement of the amount of oxygen carried by the red blood cells in your blood. This is measured as a percentage.

The optimal level of your blood oxygen saturation should be between 95% and 100%. Fitter people generally have higher blood oxygen saturation levels.

Implications of low blood oxygen level

A low level of blood oxygen saturation sustained for long periods of time is dangerous. It is best to always maintain blood oxygen levels above 95%.

Did you know?

Low levels of blood oxygen saturation occurs when:
  • When you are at a high altitude.
  • When airways react to pollutants.
  • Parameters

    Respiratory Rate

    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.

    As a general guide, fitter people often have lower normal respiratory rates.

    Breathe slowly and deeply

    While slow breathing may pose dangers, it is generally better for the average person. Slow and deep breathing have shown to bring various benefits (refer to heart rate variability for more information).

    Did you know?

    • Every minute we breathe, we take in 13 pints of air! This means we breathe about 6.15 liters of air every minute.

    • We inhale and exhale air about 22,000 times per day and in the process, transport about 300 cubic feet of air (which is about 8.5 cubic meters of air)!

    • Human breathing mechanism is called tidal breathing, as air comes out the same way it goes in.


    Heart Rate Variability

    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.

    Did you know?

    Studies shows that deep, controlled breathing helps you relaxes. When conducting deep breathing, you will feel a decrease in heart rate.

    By practising deep breathing on a regular basis, air is constantly being replaced in your lungs, and your heart rate is kept at a calm level.

    You should only practise deep breathing in a responsible manner.

    Monitoring Your

    There are many ways to gauge your fitness but no device does it like Tinké. Tinké measures your heart rate, respiratory rate and blood oxygen saturation within 30 seconds and compiles the information into a fitness score known as the Vita Index.

    When do I take a Vita measurement?

    Preferably in the morning when you just wake up, or when sitting quietly without interruptions to obtain your resting heart rate and normal respiratory rate. Both are important indicators of your fitness.

    **It is important to observe the above conditions when taking your first measurement to set your baseline for long term monitoring.

    Taking a Vita measurement:

    A waveform known as photoplethysmography (PPG) is formed when you place your thumb onto the sensing platform of Tinké.

    The shape of the PPG waveform is an important indicator of measurement accuracy. Always ensure consistent repetitive waveforms throughout the 30 seconds measurement. Retake your measurement if distorted PPG waveforms are observed.

    Monitoring Your


    Tinké measures your heart rate variability while you relax yourself with the provided breathing exercise for 60 seconds. This information is then processed into a score which indicates your level of relaxation. The score is known as the Zen Index.

    When do I take a Zen measurement?

    • Most helpful when you want to relax yourself through the breathing exercise.
    • Before going to bed to promote relaxation and calm your mind for sleep.

    Taking a Zen measurement:

    During a Zen measurement, 5 concentric circles which expand and collapse at different speed will be shown. Visually select the

    concentric circle that moves at the speed which you are most comfortable with and synchronize your breathing with it throughout the 60 seconds measurement.

    While doing a Zen measurement, you are encouraged to:

    Breathe in deeply as the circle expands, and breathe out during the collapse.

    Take your breaths all the way down to your abdomen and diaphragm rather than just your lungs. Deep breathing helps greatly in relaxation. 

    Tip: Progress to a new circle of a slower rate to practice deeper breathing. Taking slow deep breaths may help put your body further into a relaxed state.


    Vita Index

    Your Vita Index is your personalized fitness score created by piecing and analyzing data collected from your heart rate, blood oxygen level and respiratory rate. Your Vita Index allows you to conveniently know your fitness level, at a glance.

    Zen Index

    Using heart rate variability as a basis, your Zen Index indicates your level of relaxation, upon completion of the 60 seconds controlled breathing exercise. Find out how relaxed you are upon completion of the controlled breathing exercise.
