Everything you need.
Nothing you don't.
Built for people who are serious about understanding their body — not just logging numbers.
Trend Line, Not Scale Noise
A rolling smoothing algorithm cuts through daily water-weight swings to show your true trajectory — the one that actually matters.
Forecast to Your Goal
Set a target weight and ClearWeight projects your arrival date based on your real rate of change — no guesswork, just math.
Privacy First
All data lives in Apple Health on your device. ClearWeight never touches a server. Optional blur hides values in the app switcher.
Cycle-Aware Insights
Understand how your cycle phase affects your weight. Phase banners and pattern cards reveal the pattern behind the number.
Outlier Filtering
Logged a suspiciously high reading after a salty dinner? 2σ or 3σ filtering automatically dims statistical outliers so they can't skew your trend.
Body Composition
Pair weight data with body fat percentage from Apple Health for a complete picture of your composition, not just a single number.
A few screens worth seeing.
Designed for iPhone. Feels native because it is.
"I used to weigh myself daily and feel terrible about the number. ClearWeight showed me I'd actually lost 8 lbs — I just couldn't see it through the noise."
