## What is Lactate Express?

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. No more error-prone spreadsheets and manual entry.

CAPTURE — fast and error-free
• Step-test one step at a time: load (watts or km/h), lactate, heart rate, and Borg per step
• Automatic readings over Bluetooth: SensCore lactate meters and Polar heart-rate sensors
• Clear phases: rest, examination, recovery — with the current step clearly marked
• Large input fields and one-tap entry, even under time pressure during a test

ANALYZE — scientifically grounded
• Six threshold models: Mader (4.0 mmol/l), Dickhuth, LT1, dMax, dMaxMod, and user-defined fixed values
• Automatic curve fitting with coefficients and R² — the math stays transparent
• Training zones such as GA1, GA2, and EB at a glance
• Publication-grade charts

REPORT — professional
• Branded PDF reports with header and footer, charts, tables, and zones
• Share via the native iOS and macOS share sheet

COMPARE & TRACK — over time
• Compare Tests: put any two step-tests side by side (Mac and iPad) to see exactly what changed
• Home dashboard with threshold trends and deltas — an athlete's form at a glance
• Roster overview to manage many athletes from one place (Team/Pro)
• Cohort percentiles: see where an athlete ranks within the group

WHO IT'S FOR
• Diagnosticians: fast capture, athlete management, professional reports
• Athletes: clear zones instead of jargon, an honest performance snapshot

PLATFORMS
Native SwiftUI — optimized for iPad and Mac, compact on iPhone.

## Version history (last 5 releases)

### 3.0.1 — 2026-08-12

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.

### 3.0.0 — 2026-06-24

What's new in this version:
- Compare tests: place two step tests side by side on Mac and iPad and see at a glance what has changed.
- Home dashboard: threshold trends and changes show an athlete's form at a glance.
- Roster overview: keep all your athletes in one place (Team/Pro).
- Cohort percentiles: see where an athlete ranks within the group.
- Annotate evaluation charts for clearer, more meaningful reports.

### 2.0.3 — 2026-06-05
