Wearable Lactate Biosensor

Personal Project
2025

Product concept for an app connected biosensor designed to measure lactate levels in real time, helping athletes train smarter by targeting the right intensity zones. Built for endurance athletes, it provides continuous lactate data during workouts offering insights that were previously only available through invasive lab tests and inconvenient finger prick blood samples. With a continuous lactate monitor athletes can optimise performance, prevent overtraining, and fine-tune their training plans using scientifically backed metrics.

There are currently no continuous lactate monitors available, once hardware becomes available this app has potential to be connected to the hardware via SDK or API and then transfer activity metrics from smartwatches or Strava to provide enhanced performance analytics.

The following designs are initial low fidelity wireframes and concept hardware shared with athletes in user interviews for feedback.
