Body composition
Body composition tracking: weight, body fat, lean mass — without the daily anxiety.
One bad scale day means nothing. Wellness Project smooths the noise, shows you the 7- and 28-day trend that actually matters, and lets your specialists see weight in the context of training, sleep, and food, not in a vacuum.

What's inside
Body comp the way it should be tracked
Smart-scale auto-sync
Fitbit (via direct API) and Withings (via Apple Health on iPhone) flow in automatically. Any scale that writes body weight or body fat to Apple Health or Health Connect lands the same way.
Body fat and lean mass
BIA scale outputs import alongside weight. Body fat % and lean mass charted side-by-side with the weight line.
Trend-line vs daily
7-day and 28-day rolling averages overlaid on daily weigh-ins. The trend line is what we coach against, not the morning number.
Goal-aware deltas
In a cut? In a bulk? In maintenance? The dashboard shows your distance from goal and rate of change in lb/week.
Cross-domain context
Weight up 1.2 lb after a high-sodium dinner and 4 hours of sleep is not the same as weight up 1.2 lb on a normal day. Your specialists see both.
Manual entry in plain English
"Log weight 185.4." Done. No need to open the scale app.
In the app
One number is noise. The trend is the signal.
Daily scale weight bounces ±2-3 lb on water, sodium, glycogen, and sleep alone. Most apps show you the daily number and let you panic on it. Wellness Project leads with the 7-day rolling trend; the daily reading is there if you want to see it, but it doesn’t drive the conversation.
For a recomposition (gaining lean mass while losing fat), we plot body fat % and lean mass on the same chart with two y-axes. Lean mass up while body fat trends down is the recomp picture; if it’s not happening, Casey and Rex talk about why.
Smart-scale BIA is imperfect but consistent. Wellness Project doesn’t pretend a 0.5% body-fat change overnight is real; we look at 4-week deltas and call out the meaningful ones.
