K’Watch Athlete is the world’s first real-time lactic acid monitor designed to allow athletes and trainers to significantly improve training and performance without any pain. All within a sleek, premier wearable that can be worn as an armband or watch.


Lactic Acid is a key performance indicator for the body and a guide to how well muscles react to long term exertion and recovery. By understanding optimal levels of lactic acid or the “Lactate Threshold,” endurance athletes as well as explosive sports athletes and their trainers can optimize training schedules, recovery patents and ultimately performance.



Day after day your body improves thanks to hard training sessions and your Lactate Threshold changes. With K’Watch Athlete, you are able to determine your present physical limits, adjust your approaches and push your body to ensure that you are making the most of your training sessions.


Current lactic tests require cumbersome blood draws that cannot be performed during activity, resulting in thresholds being approximated based on running paces, heart rate or when someone becomes breathless. With K’Watch Athlete, people now have a way to measure this crucial indicator in real-time, with a sleek wearable device. K’Watch Athlete makes the efficient planning of training and recovery sessions an exact science.



K’Watch Athlete can be worn as a sleek designed armband and can be programmed to take continuous lactic acid readings during workouts at the push of a button. Whether you practice endurance or explosive sports you don’t have to stop exercising or training to check your levels.


From trail to 400m, from cycling to interval training at the gym, all athletes produce lactic acid. Endurance athletes will check their ability to degrade Lactic acid over a long period of time and will be very careful about recovery between 2 training sessions. Explosive athletes will benefit the most from exercising just at the right intensity, enough to improve, but not too much to cause injuries and suffer from exhaustion.



How does it work ? K’Watch Athlete is equipped with K’apsul®, utilizing a revolutionary biosensor which, in contact with the skin, tests lactate levels without any blood sample. Quite imperceptible and totally painless, K’apsul can take unlimited measurements within a 30 day period with results being displayed on the K’Watch screen as well as synced to its dedicated app.


Once the session is over, users can sync K’Watch Athlete with its dedicated app to analyze performance and cross reference results with other training indicators. Users can also track measurements over time, share them with a professional trainer, estimate optimal exertion levels and maximize performance.



The Lactate Threshold is the point at which lactate begins to accumulate in the blood at a faster rate than it can be removed. By ensuring exercise intensity is at or below this level, athletes can sustain performance with lower levels of fatigue for longer periods. Each endurance activity has a different ideal threshold range and every individual will be different. Lactate Threshold is important for endurance and sports with explosive activity such as long distance running, rowing, cycling, swimming, triathlons and obstacle races as well as any sports at the professional level.

Product will be available as soon as medical certification is being passed. This date will vary from region to region. If all developments go well, first product introduction is planned for 2018. In the meantime, you are welcomed to subscribe to our newsletter in the contact page in order to be updated about our progresses.

The K’Watch Glucose pack consists of:

  • 1 K’Watch Glucose watch
  • 1 load box
  • 1 free application

The K’Watch Athlete pack consists of:

  • 1 K’Watch Athlete armband
  • 1 load box
  • 1 free application

K’apsul is a tiny consumable that need to be plugged in K’Watch devices.

K’aspul can make unlimited measurements for a period of 30 days, after which it should be changed.

Each K’apsul integrates is composed of bio sensors and of SkinTaste® technology an array of micro-needles. At the touch-of-a button, the probes pumps a tiny drop of interstitial fluid into the K’Watch wearable device for bio-chemical analysis. While the user will feel the slight pressure of the probe pressing on their skin, they feel absolutely no pain as the sensor never reaches any nerve or blood vessel.

K’Watch is in a process of medical certification. During this process, clinical tests must be performed and officially validated, thus ensuring the accuracy of measurements.

K’Watch Glucose does not record glucose level automatically or continuously.

User need to press K’Watch on the skin before reading the result on the screen. User can however measure its glucose level as many time as he/she wants within the K’apsul‘s lifetime. He/she can also set automatic alerts on his/her K’Watch to be reminded to take measurements during the day.

K’Watch Athlete allows both on demand and continuous measurement. User just need to decide the interval between each measurement before he/she begins the recording sequence.

K’aspul is easy to insert and remove from the K’Watch watch. After 30 days of measurement, the K’aspul just need to be changed with another one thanks to the provided tool.

K’Watch can be worn as an armband, as a watch but also as a stand alone device kept in the charging box. So you can use it and continue to wear your other devices on the wrist.

We received many requests for this question so this is in the list of our projects. This is one of our priority which will require first the adult version to pass medical certification.

The K’Watch Glucose should be priced at 149 $/€

The K’Watch Athlete should be priced at 199 $/€

The K’apsul Glucose sensor, valid for 30 days, should be priced at 99 $/€

The K’apsul Athlete sensor, valid for 30 days, should be priced at 149 $/€

All these prices are subject to change, depend on local duties and taxes.

Once the medical certification process for marketing K’Watch is finalized, a second process must be initiated so that it can be reimbursed by local social security and / or insurances. Level of reimbursement will vary. We will keep you updated via our newsletter.
