Race for the Buckle

The Standings

Ranked by pace — fastest body-fat loss wins the race. Fast horses up top.

Every weigh-in, plotted. Toggle cowboys to focus the view — the y-axis re-fits to whoever's left on the trail.

The one that matters. Cross the gold line and the buckle is yours.

Mass on the scale.

For the bookkeeping.

Drop a screenshot from your scale. The AI scout reads the numbers and makes it official.

One-tap weigh-in from iOS — no screenshot needed.
