Know exactly how ready your body is today, before you train. PulseKit turns your Apple Health data into two clear daily scores: a 0-100 Recovery score and a 0-21 Strain score. It reads your HRV, sleep, resting heart rate, respiratory rate, body temperature, SpO2 and VO2 max, compares them against your own rolling baselines, and tells you whether to push hard or hold back. No chest strap, no extra hardware. Just your iPhone and Apple Watch. WHY PULSEKIT - Personalized to you. Scores are built from your own baselines, not generic averages. - Private by design. Your health data is processed on device. - Actually actionable. Every morning you get a plain answer, not a wall of charts. WHAT YOU GET - Recovery score (0-100) from HRV, sleep, resting HR, respiratory rate, temperature, SpO2 and VO2 max. - Strain score (0-21) that tracks training load from your workouts and heart rate. - Daily Why: a plain-language read on what drove today's recovery, generated privately on device. - Recovery Journal: log lifestyle tags like alcohol, poor sleep, stress, travel or sauna and see which ones actually move your recovery. - Early-warning signals that flag when your baselines drift, so you can spot the strain of illness or overtraining sooner. Informational only, not a medical diagnosis. - Trends over 7, 30 and 90 days, plus correlations between sleep, strain and recovery. - Personal goals for strain and sleep, with reminders to keep you on track. NEW IN 1.6 - Apple Watch app for glanceable Recovery and Strain on your wrist. - Home Screen and Lock Screen widgets with your Recovery ring and Strain. - A refreshed, more three-dimensional and animated interface. - A free intro offer on premium.
