Free · In-App Purchases

Capture lactate & heart rate per step, compute thresholds (Mader, Dickhuth, dMax) and training zones — pro-grade on iPad, Mac, and iPhone. Lactate Express brings the lactate step-test to iPad, Mac, and iPhone — built for performance diagnosticians and serious endurance athletes. Capture every step-test precisely, compute thresholds with scientifically recognized models, and turn them into training zones you can actually apply.

Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

What's new in this version: - Fixed unit conversion for lactate, cholesterol, ketone and uric acid: values imported from a device reporting a different unit (e.g. mmol/L) were off by an analyte-specific factor — lactate readings came in about 2x too low. Please re-check imported values from any test where your device's unit differed from the app's.
