A wearable sensor on the back of your arm, designed for up to 14 days of wear. It measures lactate in the fluid just under the skin and gives you continuous data to plan your training and pacing.
What is included?
The sensor consists of two components: a rechargeable electronics unit and a disposable patch that should be replaced every 10โ14 days. Price includes patches for an entire year.
How do we measure?
We measure lactate in interstitial fluid, the fluid just under the skin. Itโs built for training and doesnโt measure blood.
Why measure lactate?
Lactate gives a direct measure of performance intensity, while heart rate can be affected by stress, fatigue, and other external factors. Measuring lactate allows athletes to train more precisely, optimize intensity, and improve endurance faster.
Your first box includes the rechargeable sensor electronics and a full year of patches. Once your year is up, simply renew your patches , the electronics are yours to keep, forever.

How do we measure?
We measure lactate in the interstitial fluid, a scientifically validated measurement of blood lactate. A minimally invasive micro-needle, accesses the interstitial fluid painlessly beneath the skin. No blood. No sweat. No discomfort.
