Set up your phone
Prop it upright at hip height with the screen facing you. Wear fitted underwear or tight clothes, find even light and step back until your whole body fits.
3D body scan app
How does a 3D body scan app work?
In Pip Body Scan, you prop your iPhone at hip height and Pip talks you through four photos: front, both sides and back. With your agreement, the photos are sent securely to build a textured 3D model of your body. It’s usually ready in 2–4 minutes, and you can turn and zoom it.

From four photos to a 3D body
You can do it in your bedroom. Wear fitted clothes and stand somewhere with even light.
Take four photos
Pip talks you through each photo and counts you in. Face the camera, turn to each side, then turn away. You don’t need a mirror or a helper.
Pip checks each one
If you’re cut off, off-centre, tilted, blurry, in poor light or not alone in the frame, Pip asks for a retake.
Agree to the upload
Before anything is sent, Pip shows you what will upload and waits for you to say yes. Then your photos go securely to OpenAI and Meshy to build your 3D body.
Your 3D body is ready
It usually takes 2–4 minutes. You can leave the app, and Pip tells you when it’s ready. Turn it around and zoom in.
Scan again next week
One scan a week, so each check-in shows a real week of change. Later scans line you up with a ghost of your first pose.
The four photos
Each photo shows Pip a different side of you. Tap through to see what Pip asks you to do for each one.
Face the camera and let your arms hang with a small gap from your waist.
Your 3D body
Four photos in. One 3D body out.
Pip uses all four photos together to build your 3D body. Your photos are kept with each scan on your iPhone, so you can always look back at what a result was based on.
Your first scan becomes your starting point. Scan again next week and compare the two in Body Story.
Kenji is an illustrative example.
What your scan shows
Your results unlock when you join. Every number is labelled as an estimate, not a medical measurement.
A 3D model of you
A textured 3D model of your body that you can turn and zoom.
Body-fat range
An estimated range, such as 16–18%, rather than a single number.
Waist
An estimated waist in centimetres. It’s the only body measurement Pip shows.
Fat-free mass
An estimated range in kilograms. Fat-free mass isn’t the same as muscle.
Compared with others
Roughly where you sit against US adults of your age and sex. Not shown if you’re 60 or over, or haven’t given your sex.
Four signals
Leanness, definition, upper body and lower body, each scored out of 100 and tracked week to week.
Accuracy limits
It’s an estimate from photos.
Pip’s 3D body is a model of your outside shape. It isn’t a medical scan. Body-fat and waist figures are AI estimates, not medical measurements.
Pip doesn’t measure muscle. There’s no BMI, visceral fat or metabolic age score, because four photos can’t measure them. Clothing, pose and light all change the result, so scan in the same spot, in similar clothes, at a similar time of day.

Body Story lines up your weekly scans. Compare any two side by side, overlaid, or with a before-and-now slider.
Your photos and 3D bodies are stored on your iPhone, protected and left out of backups. Delete everything in one tap.

Questions
Short answers about the 3D body scan.
Do I need LiDAR or a newer iPhone?
No. The scan uses the normal front camera. It doesn’t use LiDAR or depth. You need an iPhone with iOS 17 or later.
How long does a scan take?
Taking the four photos takes a few minutes. Building your 3D body usually takes 2–4 minutes after that. You can leave the app, and Pip tells you when it’s ready.
How often can I scan?
Once a week. Your next scan opens seven days after your last one, so each check-in shows a real week of change.
Is the scan processed on my iPhone?
No. Your 3D body is built in the cloud, after you agree. Your four photos and basic body details are sent securely to OpenAI and Meshy. The finished body is stored on your iPhone, and Meshy’s copy is then deleted.
Is there a free trial?
No. You can take your first scan for free, but the results stay hidden until you join. Membership is weekly or monthly through your Apple ID, and you can cancel in your Apple subscription settings.
Is Pip Body Scan on Android?
No. Pip Body Scan is for iPhone only and needs iOS 17 or later. There’s no Android, iPad or Mac app. Android is planned, but there’s no date yet.
Pip Body Scan is coming soon.
It’s coming to the App Store for iPhone. Your first scan will be free to take, and you’ll need a membership to see your results.
