A public record of everyday movement

How movement changes over a life. Yours, and everyone's.

Health data you can find is either a snapshot or a countdown. This is neither. Living Life Data draws the slope: how the daily movement of ordinary people changes as they age, and where your own line sits against it. People contribute from the phone they already carry. We aggregate. Everyone sees the same map.

Daily steps across a life

Demo data

Your 26-week mean, drawn against the median of people currently each age. Steps per day.

The dashed line is cross-sectional: the people who are 75 today, not your future. People who stayed active are over-represented at older ages, so an individual's real slope is usually steeper than this sketch. As contributors stay on the map for years, real within-person slopes replace the sketch and this chart gets truer. Steps describe movement, not health.

Your week

One card a week. No streaks, no rings, no verdict.

Daily numbers are noise. A week is the unit people think in. The card shows your week, your age group's week, and how this week sits against your own last twelve. The population is the story; your number is a footnote.

Demo data

Contributors aged 60 to 69, by 4-week mean daily steps. Your line is your own 4-week mean.

The whole distribution is shown, not a rank, because a rank pushes people below the middle away from the map. Shown only when the cell has at least 50 contributors.

How it works

Contribute once. Then live normally.

Install and choose

Read what the project is, pick which measurements to send (steps, distance, optionally resting heart rate), and give the phone's health store permission. Age bracket and broad region are optional, asked once, with the reason stated.

Your phone does the rest

Daily summaries sync in the background from Apple Health, and later from Android Health Connect. No logging, no extra exercise, no watch required. You can see exactly what was sent and when.

The map updates on a schedule

Released snapshots, not live queries. Every cell has at least 50 contributors or it is not shown. Definitions and release dates sit beside every chart.

Stop any time

Pause, export, withdraw, or delete from inside the app. Each control says exactly what it does and what it does not. Privacy and control.

The whole cohort, at a glance

A contributor-day is one person on one date with at least one valid measurement. Person-years are contributor-days divided by 365.25 and do not imply continuous wear. How every number is counted.
