Currently in beta · early access

Coaching powered by real physiology.

The Be app builds your training around your lactate zones, training load and recovery, then adapts it daily to how you're responding. It's in beta now, so access is invite-only for the moment.

Real LT1 / LT2 zones
Blood lactate ramp tests with Dmax curve fit. No HR% estimates.
Transparent rationale
Every session explains why, based on load state, HRV and race proximity.
Blood markers panel
Iron, hormones, vitamins, RED-S screen. All tracked in-app.

How it works

From first test to your best block yet.

Four steps from sign-up to a plan that adapts with you. We test first, because everything that follows depends on real zones.

01

Test your physiology.

Lactate ramp test in-app. A Dmax curve fit identifies your true LT1 and LT2. These are the thresholds that actually drive training, not heart-rate estimates.

Connect your devices.

Garmin, Strava, Apple Watch, Apple Health. HRV, sleep, resting heart rate and training load all sync automatically. No spreadsheets, no manual entry.

The app builds your plan.

Evidence based periodisation, shaped around your lactate zones, your schedule and your race. It auto-adjusts when your readiness data says recover.

Monitor & adapt.

Every morning, readiness gates the day. Blood markers track long-term: iron, hormones, vitamins, RED-S screening. Progress you can see, not just feel.
