The Body Electric
Section titled “The Body Electric”Live at: https://body.quarterly.systems
A weight tracking app that cuts through daily fluctuations to show you what’s really happening with your weight trends.
What It Does
Section titled “What It Does”Most weight apps frustrate you with daily ups and downs caused by water retention, meal timing, and other noise. The Body Electric uses statistical smoothing (EWMA) to reveal your actual weight trend, helping you make better decisions about diet and fitness.
It also estimates your calorie surplus or deficit based on trend changes, giving you actionable insights without complicated food logging.

- Data-minded individuals who appreciate science-based metrics

Common Questions
Section titled “Common Questions”Why does my weight jump around so much? Water retention, food in your system, sodium intake, and hormones all cause daily swings of 2-5 lbs. That’s normal!
How long until I see my trend? You’ll see a trend line immediately, but wait 5-7 days for it to become meaningful.
What if I miss a day? Not ideal, but the trend will still work. Just weigh yourself as soon as you remember.
Is my data private? Yes! Everything stays on your device in your browser. No cloud sync, no accounts, complete privacy.
Can I use pounds or kilograms? Both are supported - choose your preferred unit.
What’s EWMA? Exponentially Weighted Moving Average - a statistical method that smooths noisy data while staying responsive to real changes. You don’t need to understand it for it to work!
