Withings
Your Withings scale, read by an AI coach that tracks the trend, not just today’s number.
Withings connects directly to Wellness Project over its own API, not through Apple Health or Health Connect. Every step-on reads weight and body composition into your record, and Casey, Evelyn, and Max read it alongside your training, food, and sleep.

What's inside
What a Withings scale gets you
Weight, every reading
Each step-on lands as its own reading. Wellness Project keeps the latest value per field for the day, so a morning weigh-in never gets erased by an evening one that only measured weight.
Full body composition on a Body Scan or Body Cardio
Body fat percentage, fat mass, lean mass, muscle mass, bone mass, hydration percentage, visceral fat rating, and BMI, on scales that measure them. A weight-only scale still logs weight.
Sleep, from a Sleep Analyzer or ScanWatch
Total sleep, sleep score, deep/REM/light stages, and awakenings on nights Withings actually measured a session. No session, no invented night.
Resting heart rate and HRV from sleep
Read from the same overnight session: lowest heart rate, and heart rate variability from the reading closest to waking when your device reports it.
Steps, Active Zone Minutes, and workouts
Daily steps and heart-rate-zone minutes from an activity tracker, plus any logged workout (walk, run, cycling, swim, strength, and dozens more) imported as a structured session.
Automatic sync, read-only
Withings notifies us the moment a new reading exists, and that notification pulls it in server-side, so a weigh-in usually lands before you have put the phone down. A roughly hourly poll and a refresh when you open the app cover anything a notification misses. We only ever read your data; nothing is written back to your Withings account.
In the app
A scale that remembers, not just a scale that weighs
A Withings scale is precise, but a single number on a single day is noise. Wellness Project takes every reading and builds it into a trend: how your weight actually moved this month once you strip out water-weight swings, whether muscle mass is holding while fat mass drops, whether last night’s short sleep is why this morning’s number looks off.
Casey Mills (nutrition) reads your weight and composition trend against your goal without moralizing about a single number. Evelyn Cross (longevity) treats body composition and sleep as long-horizon signals, not daily scorekeeping. Max Kline (biohacker) reads your HRV and sleep data the way he reads any wearable feed, looking for what actually moved the needle.
