Heart
Heart rate and HRV
compared with
your baseline
Heart rate, HRV, and overnight dynamics — compared with your usual range, not a single day's reading.
The signal is
in the trend shift
Arry compares today's heart rate and HRV with your usual range and recent trend. One day is noise; a sustained shift is a signal.
Now and overnight
Current heart rate
and overnight trend
Live heart rate
Your current heart rate updates while this screen is open; measurement history is one tap away.
HRV
Today's HRV and recent trend are compared with your usual range.
Resting heart rate
A morning reading makes sustained shifts visible before they become obvious.
What to notice
Changes
by day
and overnight
Heart age
An estimate from resting heart rate, HRV, and age — the difference from chronological age.
Overnight curve
The shape of heart rate overnight: a recovery dip, flat line, rise, or broken sleep.
Resonance and coherence
How steady your heart rhythm is at rest. High resonance comes with slow, calm breathing; data from Apple Watch.
Cardiac load
Accumulated load on the heart from heart rate across the day, and its balance with recovery.
Warning
HRV, temperature, resting heart rate, and SpO₂ deviate together — Arry flags the risk and suggests reducing load.
Today's pattern
A personal pattern from your heart rate and HRV history to consider today.
Apple Health

Arry reads cardiac data from Apple Health and processes it locally on your device.
