Get Koach and make the commitment to move better to unlock your true potential day after day !















The hardware part to objectify the movements methods

Koach consists, on one part, of a high performance sensor to collect accurate data from your lumbar spine.

  • The 3-axis accelerometer allows Koach to identify the forces on the pelvis and the body translation movements.
  • The 3-axis gyroscope allows Koach to identify the moments on pelvis and the body rotation movements.
  • The 3-axis digital compass allows Koach to localize the pelvis in respect of magnetic poles.
  • The barometric altimeter allows Koach to calculate the altitude of the pelvis.
  • The embedded Memory allows Koach to store data in offline mode. Koach stores movements data at 0.05 second intervals.
  • The Wifi connection allows Koach to synchronize data directly with our cloud via your personal wireless network.
  • The Bluetooth 4.0 Connection allows Koach to synchronize data with your phone or your computer.
  • The Double Processor allows Koach to manage wireless connections and to embed linear indicators computing.
  • The Battery lasts up to 17h. It is made of lithium-polymer. Its charge time is 20 minutes.

An eco-friendly design to prove that we can do both technology and care about environment

The sensor case

The case has the curved shape of the spine to perfectly fit with its movements. It is made of acrylonitrile butadiene styrene (ABS) which is a common renewable thermoplastic polymer.

The belt

The belt is made of organic cotton.

The artificial intelligence part to recommend you the right exercise at the right time

Science of Movements

The Koach 9-axis sensor and cutting-edge algorithms capture relevant indicators through core body movements. To determine these key metrics to unlock your true potential, Koach is based on medical research and experiments in yoga sessions. This state-of-the-art research has created new knowledge about moving technique, identifying characteristics for more efficient moves and poses.

Core Muscles

Your body’s core muscles are located mostly in your back, abdomen and pelvis. This group of muscles provides the foundation for movement throughout your entire body, and strengthening them can help protect and support your back, making your spine and body less prone to injury and helping you gain greater balance and stability.

Hence the importance of an active lifestyle punctuated by daily stretch routines and reinforcement exercises in order to maintain and strengthen our back muscles.



So far, 34 key indicators have been designed. Here are the five most important ones:


Balance, measured as a linear function of angles, is the indicator used to describe the ability to maintain the line of gravity of the body within the base of support with minimal postural sway. A lack of balance can provoke falls and wrong movements. Koach will help you improving your balance by recommending exercises such as jumping jack for example.


Stability, mesured as a non-linear function of angular speeds, is the indicator used to describe the amount of postural sway at which balance is lost and corrective action is required. A lack of stability can provoke disability to do some movements and injuries. Koach will help you improving your stability by recommending exercises such as yoga poses.


Fluidity, mesured as % of ideal movement, is the indicator used to describe the smoothness or elegance of the movement. A lack of fluidity can add physical restraints on joints. Koach will help you improving your fluidity by recommending exercises such as Tai-Chi movements.


Verticality, mesured as two angles with the horizontal axis, is the indicator used to describe the upright position of the back. A lack of change in verticality is the sign of harmful postures and can provoke pain in the lower back. Koach will help you change your verticality by recommending you preventive stretching exercises.  


Shocks, mesured as magnitude, is the indicator used to detect unusual changes in your physical behavior. Too many shocks can cause deterioration of your physical capital and cause musculoskeletal disorders. Koach will help you avoid exceeding shocks by recommending to stop an activity if necessary.

Koondal creates solutions combining hardware, artificial intelligence, physiotherapy expertise to develop physical capabilities. Whether you’re an elite athlete, an everyday layabout, or somewhere in between, chances are you will eventually deal with back pain.  And while a typical response to experiencing back pain is to take it easy, either by laying down and gulping on antalgics or stopping any strenuous activity, this approach can undermine the healing process.

Studies show that the best prevention and recovery strategy is a combination of body awareness and physical exercises. 

Koondal stems from the sanskrit word "kundalini" in the concept of Dharma, refers to a form of primal energy said to be located at the base of the spine.

Koondal has offices in Paris (France) and Belgrade (Serbia).
