HeartStress: HRV & Heart Rate

One simple score for today's heart load and recovery — processed on device, no account required.

HeartStress turns your Apple Health signals into one simple daily score for heart load and recovery, so you can see how today is going at a glance.

WHAT YOU GET • A daily heart-load score with a warm, plain-language read on today. • The signals behind the score: HRV, resting and night heart rate, sleep, and activity. • 7, 30, and 90-day trends so you follow the pattern, not just one day. • Gentle alerts when high load or under-recovery keeps showing up. • A shareable PDF report that summarizes key days, drivers, and recovery notes. • An Apple Watch app and complication to check your score right on your wrist.
