Heart metrics are here!

Klenz now reads Resting Heart Rate (RHR) and Heart Rate
Variability (HRV) from Apple Health and learns what's normal
for you

■  RHR & HRV on your home screen, compared to your own baseline
■  Tap through for daily charts: a heartbeat-style view for resting HR, a beat-gap view for HRV
■  Your usual range drawn on every chart, so changes are obvious at a glance
■  Plain-language explainers for what each metric actually measures

Give it about a week of readings to calibrate to you.
