See your current load, fitness, fatigue, form, recovery, intensity balance, and efficiency—then explore the charts behind every signal.
Current state, recovery-aware readiness, recent volume, and exact load-model values in the same hierarchy used by Training.
See how Form, freshness, intensity, efficiency, and power change over time, with readiness, recovery, and sleep views available in Training.
Start from a preset or arrange Curated, KPI, Custom, and Map tiles yourself. Each tile keeps its own filters; maps add style and marker-clustering controls.
Compare heart rate, power, altitude, depth, pace, and more in synchronized charts. Inspect intensity zones, grade-colored elevation, inverse depth, aerobic durability, and cadence versus power. Switch between distance, duration, or time where supported, then select a range for stats or zoom in.
Explore sleep, readiness, training, measurements, and recent activities in one conversation. The Assistant answers from your current data—not generic fitness advice.
Start with today, a trend, or a recent workout. Ask follow-up questions without starting over.
The Assistant draws from sleep, recovery, training, measurements, and activities when your question needs the broader context.
Each answer shows the data behind it, so you can see exactly what supports it.
Your data, current evidence, conversational answers.
Connect ChatGPT or Claude through read-only MCP. Ask them to analyze your training, review your season, plan your next workout, or draft a longer training-plan proposal grounded in your load, fatigue, readiness, sleep, measurements, workout charts, and routes. You choose the data; neither tool can add workouts or change your account. Location access remains separate.
Compare same-session recordings from watches, bike computers, and sensors. Set reference and test devices, auto-align their timelines, and turn GNSS and sensor differences into repeatable evidence.
