Scan with LiDAR
A friend circles you with the iPhone for about a minute. A live LiDAR view shows what's captured and where the gaps are.
For iPhone with LiDAR
100% on-device
See your progress in 3D.
Scan your body as often as you like, compare scans side by side, and measure your waist, hips and chest right on the model.
Your body never leaves your iPhone.
Scanning, building your 3D model and every measurement happen entirely on your phone. No uploads, no cloud, no server ever sees your scans.
Free to store up to 10 scans, and redoing a scan never counts against you. Premium stores unlimited scans, with the first month free.
The mirror doesn't show the whole story.
Change is slow and easy to miss day to day. Regular 3D scans make it visible, and measurable.
A true-size 3D model
Every scan becomes a textured 3D model sized to real life, organized in folders by pose: relaxed, double bicep, side chest.
Measure on the model
Tap to wrap a measuring ring around your waist, hips, chest, arms or legs, then slide it along the body to find the spot you want.
Compare side by side
Put two scans next to each other, standing on the same floor at the same scale, and measure both.
Track over time
A countdown to your next scan, your weight trend, and Explore to see your weight by folder, condition and period.
Ask Siri
"How has my weight changed in My Progress Buddy?" or "When is my next scan?" Answers come from the data on your iPhone.
Real, not rebuilt
Your real body. Not an AI guess.
Many body-scan apps take a few photos and let AI reshape a generic avatar to fit. My Progress Buddy measures you: the LiDAR depth sensor maps your actual shape, and your own photos are wrapped onto it, so the model you see is you.
My Progress Buddy
- Shape measured with LiDAR depth, from hundreds of camera angles
- Textured with your own photos: your skin, your clothes, your details
- True size, so the measurements are of your body
- Built entirely on your iPhone. Nothing is uploaded
Typical AI avatar
- Shape estimated from a few photos and a body model
- A smooth, generic figure, not your actual surface
- Numbers predicted by a model, not measured
- Often processed on a company's servers
Compare
Compare measurements and progress
Put any two scans side by side, standing on the same floor at the same true size, so the difference you see is real.
Same scale, same floor
Both models stand on the floor at their measured true size, so a bigger waist on screen is a bigger waist.
Movable rings to compare measurements
Place a measuring ring on each scan and slide it up or down the body. Line both up on the same spot, like the belly button, and read the change.
Same spot in one tap
Measure one scan, then tap Same spot and the other scan's ring jumps to the matching place, so every check is like for like.
How it works
A few minutes a scan. Capture as many poses as you like, group them in folders, and scan again in a week, a month, or whenever suits you to see your progress.
Stand and pose
Stand about 5 feet from your helper in bright, even light and stay completely still until the scan ends.
Circle and scan
Your helper walks slowly around you in a few passes, upper body first, then working down. Keep the scan if the LiDAR view has no holes, or redo it.
See and measure
Your 3D model is built right on your iPhone. Measure it, log your weight, and compare it with last time.
Stay absolutely still
Even a small shift or drifting arms can blur the model. Keep heavy breathing to a minimum, pick a pose you can hold, and don't move until your helper finishes.
Better light, better model
Bright, even light gives a sharper, more complete model. Avoid dim rooms, strong shadows and bright windows behind you.
Tie long hair up
Loose hair covers your neck and upper back, so those parts come out patchy. A bun or ponytail up high keeps them clear to scan.
Take more than one pass
One lap is rarely enough. Focus the first pass on the upper body, then work lower with each pass. Keep the whole body in frame, and step closer for spots like under the arms and between the legs.
Private by design
Your scans stay yours. Completely.
Body scans are about as personal as data gets. So My Progress Buddy does all the work on your iPhone, using its own chip, and never sends your scans anywhere.

Questions
Which iPhones work?
Scanning needs an iPhone with a LiDAR sensor: iPhone 12 Pro, 12 Pro Max, and every newer Pro and Pro Max model. On other iPhones you can still view, compare and measure scans.
Do I need someone to help?
Yes. A second person holds the iPhone and walks around you while you hold a pose. It takes about a minute.
Is the 3D model really me, or an AI avatar?
It's really you. The shape comes from your iPhone's LiDAR depth sensor measuring your body from every angle, and it's textured with your own photos. Nothing is guessed by AI or reshaped from a template, which is why the measurements reflect your actual body.
How accurate are the measurements?
They're built for tracking your own change over time: scan in the same pose, place, light and clothing, and compare like with like. Each reading is checked against the scan's depth data and marked Supported or Low confidence. They aren't medical measurements.
Where are my scans stored?
Only on your iPhone. If you delete the app, its scans are deleted too. They're included in your iPhone's own iCloud or computer backups if you have those turned on.
Are my body scans uploaded to a server?
No. Scanning, building the 3D model and every measurement happen entirely on your iPhone. Your photos, depth data and models are never uploaded, and the app works offline.
How much does it cost?
Storing up to 10 scans is free. Scans you redo or discard don't count, so you can retake one as often as you need. To store more than 10, Premium is $4.99 a month for unlimited scans, with the first month free. It renews through your Apple ID until you cancel.
How often should I scan?
As often as you like. Many people scan every week or two, or once a month. Home counts down to your next scan on the schedule you choose, and you can scan any time.
Can I scan more than one pose?
Yes. Capture as many poses as you like, such as relaxed, double bicep or side chest, and group each pose in its own folder so later scans compare like with like.
Do I need an account?
No. Premium is tied to your Apple ID, so it follows you to a new iPhone. Use Restore Purchases in Settings if needed.
