Built for the long way down.

Daily weight is noisy. Downhill smooths it into a trend you can actually steer by.

Log it in two seconds

A ruler, not a keyboard. Slide to your weight, tag it fasted or post-run, done before the kettle boils.

The trend, not the noise

Water, salt, and sleep bounce the scale around. The 7-day trend line cuts through it — that's the number that matters.

89.0 On pace · Oct 12 79.0
