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

01

Heart age

An estimate from resting heart rate, HRV, and age — the difference from chronological age.

02

Overnight curve

The shape of heart rate overnight: a recovery dip, flat line, rise, or broken sleep.

03

Resonance and coherence

How steady your heart rhythm is at rest. High resonance comes with slow, calm breathing; data from Apple Watch.

04

Cardiac load

Accumulated load on the heart from heart rate across the day, and its balance with recovery.

05

Warning

HRV, temperature, resting heart rate, and SpO₂ deviate together — Arry flags the risk and suggests reducing load.

06

Today's pattern

A personal pattern from your heart rate and HRV history to consider today.
