Continuous Lactate monitoring
designed for athletes

Monitor your lactate level in real time without pricking your finger.


K’Watch Athlete is the world’s first real-time lactate monitor designed to allow athletes and trainers to significantly improve training and performance while reducing the risk of injuries. 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 patterns, and ultimately, performance.



Day after day, your body improves and your Lactate Threshold changes, thanks to hard training sessions. 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 or at your wrist. It measures in realtime your lactic acid level. 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, when 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 iOS or Android 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 that 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.

K’Watch is not yet available on the market. It is still under development and needs to get medical certification.
