Signal connects to your Garmin devices and uses Claude AI to synthesize HRV, sleep quality, training load, GPS data, and body metrics into a single daily performance brief — so you train with intent, not guesswork.
What Signal Does
HRV trend, resting HR, and sleep efficiency combined into a single 0-100 readiness score. Know before you lace up.
CTL, ATL, and TSB calculated from every activity. Surface the fitness-fatigue balance before overtraining becomes injury.
Every morning, Claude synthesizes your Garmin data into plain-language insights: what's working, what needs rest, what to target today.
"HRV down 8ms vs 7-day avg. ATL elevated. Recommend Z2 only today — your fitness is solid, protect it."
Visualize every run and ride on interactive maps. Analyze elevation, pace splits, and heart rate overlaid on your actual GPS track.
Signal AI Coach
HRV is trending 11% below your 30-day baseline and you recorded only 5h 40m of sleep. Your ATL is elevated from Tuesday's threshold session. Today is a recovery day — a 40-minute Z2 run or rest. Tomorrow's long run window looks optimal if you recover well.
