How it works

Stand, hold, and let your phone do the science.

Balance Matters uses your phone's built-in motion sensors to quantify postural sway. No wearables, no setup — just three quick poses.

01

Place & press start

Slip your phone in your pocket or hold it to your chest. Tap start when you're ready.

02

Hold each pose

Three short stances measure sway across stability, vision, and proprioception.

03

See your score

Get an instant balance score and watch it trend over days, weeks, and months.

The protocol

Three poses. One reliable score.

Each pose challenges a different system that keeps you upright. Together they paint a complete picture of your balance.

Pose 1

Feet together

The baseline. Eyes open, feet side-by-side — measures your fundamental postural sway.

10 seconds
Pose 2

Left foot forward

Tandem stance with your left foot in front — narrows your base and challenges lateral stability.

10 seconds
Pose 3

Right foot forward

Tandem stance with your right foot in front — reveals side-to-side asymmetry in your balance.

Steps

Are you moving enough? Active days correlate with steadier scores.

Sleep

Poor sleep destabilizes balance. We surface the link, night after night.

Heart rate

Resting and active heart rate add cardiovascular context to your score.

Why balance matters

Falls aren't accidents. They're a signal.

One in four adults over 65 falls each year. Balance is the earliest, quietest predictor — and the easiest to retrain when you measure it consistently.
