Know when to push and when to rest.

COR5 reads your heart and body in minutes and tells you what really matters today: are you ready for a hard workout, how well did you recover, and how is stress affecting you. No guesswork, no generic plans – just your body's own signals.

START YOUR DAY WITH A QUICK CHECK
Sit still for a short check and get a clear picture of your stress, energy and readiness. Over time COR5 learns what's normal for you and highlights results outside your usual range.

TRAIN SMARTER
See your heart rate and personal training zones live during every workout. After the session you get a score, your training load and a clear answer to the most important question: how much recovery do you need before the next one?

RECOVER BETTER
A short check after training shows how far your body has bounced back. Stop overtraining, stop undertraining – train when your body is ready.

UNDERSTAND YOUR BODY
• Track body fat, muscle mass and hydration
• Check your balance
• See how your heart responds when you stand up
Everything in one app, from one small sensor.

SEE YOUR PROGRESS
Trends over days and weeks show whether you are getting fitter, more rested and less stressed. Easy-to-read reports and AI insights explain your results in plain language, and you can share them with your coach in a tap.

ONE SENSOR, MANY SIGNALS
The COR5 sensor sits on a chest strap during workouts or rests in your hands for daily checks. It captures your heart's activity, blood oxygen, motion, body composition and skin temperature – the kind of data that usually takes several devices.

BUILT FOR ATHLETES AND COACHES
Pro mode adds extended readiness and recovery tests for serious training.

Requires the COR5 sensor (sold separately).
