Your Apple Health data already knows a lot about you. Korte helps you understand what is actually changing.
Korte turns your health and training history into a clear view of your fitness, cardiovascular health, recovery, sleep and training — without reducing your body to another arbitrary daily score.
SEE HOW YOU'RE CHANGING
Follow your performance across weeks and months. Korte separates meaningful trends from normal day-to-day noise so you can see what is improving, holding steady or moving in the wrong direction.
PERFORMANCE AGE
See your current performance through an intuitive age-based estimate and follow how it changes as your fitness evolves.
HEART AGE
Understand your cardiovascular standing and how it is changing over time using the health signals available to Korte.
YOUR EVOLUTION
Follow the capacities behind your performance, including cardio, recovery and training consistency. Korte focuses on direction — not isolated measurements.
UNDERSTAND TODAY
See your available HRV, sleep, resting heart rate, VO₂ max, respiratory and training signals in context.
Korte doesn't manufacture an insight every morning. When nothing has changed meaningfully, it tells you.
SEE YOUR TRAINING STIMULUS
Understand where recent training demand has been concentrated and how your training emphasis is shifting over time.
ASK YOUR OWN HISTORY
Korte Coach lets you explore your own health and training data.
Ask questions like:
• Why is my Performance Age changing?
• How is my heart improving?
• Compare my last session to the one before.
• How has my sleep changed this month?
BUILT AROUND APPLE HEALTH
Korte works with supported health and workout data available through Apple Health, bringing signals that normally live separately into one longitudinal view.
LESS NOISE. MORE SIGNAL.
Your body doesn't reset every morning.
Korte is built to help you understand the direction you're moving.
