Contura 4.0 — Your Body, Finally Visible

There’s no shortage of tools for logging body data. You can type your waist, hips, and weight into any spreadsheet-style app and watch the list of numbers grow.

But numbers are abstract. “Waist: 78 cm” doesn’t make you feel anything, and when it drops to 76 cm next month, it’s hard to actually see where those two centimeters went.

That’s exactly what Contura 4.0 is built to solve. We’ve redefined Contura as a body-measurement tracker — but what sets it apart from every other app in the category is this: throughout the entire process of entering your data, a 3D body that reshapes itself in real time stands at the center of your screen. You’re not filling in a form. You’re sculpting a version of yourself you can actually see.

This time, we rebuilt the whole experience end to end around four tabs — Measure, Progress, Insights, Profile.

A 3D body that changes with you

Let’s start with the thing that makes Contura different: the 3D body model.

This isn’t a static picture, and it isn’t a handful of preset “before/after” silhouettes. It’s a high-order parametric 3D body that deforms naturally and continuously in response to every measurement you enter, in a way that follows how real bodies are built. Add a little to your waist and the model’s waist genuinely fills out; change your shoulder width and the V-taper of your torso changes with it.

So in Contura, numbers finally have a shape. You no longer have to imagine what “a 78 cm waist” looks like, because that body is right in front of you — rotate it, and study it from any angle.

This model runs through the entire app — from the moment you log your data, to looking back at the past, comparing your progress, and reading your insights. It’s always the same body, holding the same pose and the same camera. Switching tabs feels like flipping through chapters of the same book.

Measure: see the result as you enter it

Measure is Contura’s home base, and the screen you’ll spend the most time with.

Tap the plus button in the bottom-right corner and a set of body-part cards appears — every part you want to track. Tap any one, and enter your latest measurement by sliding through the options and numbers.

Two details make all the difference:

It tells you where to measure. A lot of people don’t measure inconsistently because they can’t use a tape — it’s because they measure in a slightly different spot every time. One day at the navel, the next at the narrowest point, and the numbers wobble for no real reason. As you log, Contura highlights the correct measurement location right on the 3D model, and you can rotate the model to double-check. Measure the same spot every time, and the trend finally means something.

It reshapes itself as you type. As you drag the slider to adjust a circumference, the body model above updates in sync — growing or shrinking. You feel the body behind that number, instantly and intuitively. What you see is what you get.

The top-right corner of the Measure tab hides a timeline slider. Drag it, and you can scrub back to any day in your history — the 3D body immediately switches to that day’s data and shape. One finger, and you can travel up and down the timeline of your own body.

Progress: red is gain, blue is loss

Put today next to the past, and change reveals itself. That’s the job of the Progress tab.

Progress shows your body change in a way we call red/blue volume: volume gained appears in red, volume lost appears in blue. Both directions, on the same body, at the same time. Even a one-centimeter difference is marked clearly — the subtle changes the mirror can’t show you are obvious here.

By default, Progress compares your first day on Contura to today, so you can see at a glance how far the journey has come.

And you can customize all of it:

Tap the top-right corner to switch between red/blue volume, side-by-side, overlay, and other comparison views — pick whichever reading suits you best.
Reselect which two moments to compare — say, “the day my waist was biggest” against now, or “the period when I was lightest” against now.

Every moment in your body’s history that’s worth remembering can be pulled up at any time and placed beside the present.

Insights: understand your body, then have it read back to you

If Measure and Progress are about seeing, Insights is about understanding. It’s the deepest screen in Contura 4.0, and it takes you down layer by layer.

The Body Shape radar. At the top is a radar chart of every circumference across your body — one look tells you the current state of every part. This radar is normalized: instead of plotting raw numbers onto axes, it converts them, so the shape itself carries meaning. The closer it is to a circle, the more proportionate your body. You can overlay past data to see whether you’re trending toward a more balanced shape, or toward a more distinctive, more aggressive one.

A trajectory with a future forecast. Further down is a freely switchable trajectory chart. Pick a part or dimension you care about, and you’ll see its clear path over the recent past. Going further, we extend that trajectory into the future with an algorithm — the chart shows a fan-shaped shaded region representing the confidence range: where your body is most likely to land. You don’t just see where you came from; you see where you’re heading.

Proportion Analysis. Next comes a set of body-proportion metrics — waist-to-height ratio, waist-to-hip ratio, and more. More than any single circumference, proportions tell the real story, because they’re about how your parts relate to one another.

12 advanced body metrics. Then come the advanced numbers for people who take their bodies seriously — 12 metrics in all, each with a plain-language explanation, reference ranges, and the science behind it:

Waist-to-hip ratio (WHR)
Waist-to-height ratio (WHtR)
Body fat percentage
Fat-Free Mass Index (FFMI)
A Body Shape Index (ABSI)
Adonis Index
Relative Fat Mass (RFM)
Basal Metabolic Rate (BMR)
Conicity Index (C-Index)
Metabolic Age
Body Surface Area (BSA)
Somatotype Radar (Endomorph · Mesomorph · Ectomorph)

The Deep Body Report. At the very bottom of this screen sits a Deep Body Report. We worked with professionals to build the content framework, turning all those charts, proportions, and metrics into a passage of natural, readable language — no longer cold data, but more like someone sitting across from you and walking you through where your body stands right now. The report can be shared in a single tap with your coach, a friend, or anyone you’d like to bring along on your progress.

Profile: everything in its place

The fourth tab, Profile, holds all of your personal options — unit preferences, goals, reminders, health-data sync, subscription, and privacy. It sits quietly in the corner, always there when you need it.

Why Contura isn’t like other measurement apps

In the end, the difference comes down to a single sentence: other apps store your body as a spreadsheet; Contura restores it to a body.

Others give you a list of numbers; Contura gives you a 3D body that reshapes with those numbers.
Others leave you guessing “where do I measure this time?”; Contura shows you, right on the model.
Others tell you “you lost weight” with a line chart; Contura uses red/blue volume to tell you “this is where you lost it.”
Others stop at “past to present”; Contura uses a confidence range to tell you “this is where you’re heading.”
Others hand you a pile of metrics; Contura turns them into a report you can actually read.

Managing your body is a long game. And what keeps people in it has never been more numbers — it’s stronger, more visible feedback. That’s what Contura 4.0 is here to give you.

From 2.0 to 4.0: a complete rebuild

If you’re a longtime user who’s been with Contura since 2.0, you’ll find 4.0 is very nearly a brand-new app. The 3D engine, the logging flow, the way you compare, the insights system, the report generation — every piece has been redesigned and refined. We didn’t add bricks to the old foundation; we rebuilt the whole house around one idea: make the body visible.

Contura 4.0 is the version we always wanted to build. Thank you for being here to see yourself, clearly, with us.

If you love it, a review on the App Store means the world to us. And if anything falls short of what you expected, we read every single message.
