Kairex: Readiness & Recovery

Your body makes a call every morning: push hard or go easy. Kairex reads your Apple Health data and tells you what it says: measured, not guessed.

Kairex reads your Apple Health data: sleep, heart rate variability (HRV), resting heart rate, steps and more: and tells you every morning how ready your body really is. Let your body decide, not the calendar.

READINESS SCORE One number from 0 to 100 built from your sleep, HRV and resting heart rate. High score: a good day to go for a personal best. Low score: put recovery first.

MORNING BRIEFING A short, personal summary of your night: how hard to train today and what to watch out for.

SMART SUPPLEMENT IDEAS A prioritized supplement list based on your age, goal, training history and, if you add them, your blood test results. AI writes a personal reason for every suggestion.

NUTRITION & CYCLE TRACKING Daily macro tracking, plus optional menstrual cycle tracking with workout suggestions for each phase.

TRAINING & RECOVERY Muscle-group recovery estimates, automatic comparison with your last session, and early deload suggestions when your load climbs too fast.

STRAVA Runs and rides you record in Strava count toward your readiness too.

APPLE WATCH See your readiness score and daily supplement reminder on your wrist.
