Waist tracker

How does Pip Body Scan track your waist?

Pip Body Scan estimates your waist in centimetres from four guided photos. You can scan once a week, and each scan gives a new estimate, so you can compare your waist from week to week alongside your 3D body. It’s an AI estimate from photos, not a tape-measure reading or medical measurement.

What the waist tracker shows

Your results unlock when you join. Every figure is labelled as an estimate.

01

Waist in centimetres

Each weekly scan gives an estimated waist, worked out from your four photos.

02

Week to week

Scan once a week and compare your waist estimate with earlier weeks.

03

Next to your 3D body

See the estimate beside a 3D model of your body, so a number never stands on its own.

04

With your body-fat range

The same scan gives an estimated body-fat range and fat-free mass.

05

Compared with others

Roughly where your waist sits against US adults of your age and sex. Not shown if you’re 60 or over, or haven’t given your sex.

06

Fair comparisons

Scan in the same spot, in similar fitted clothes, at a similar time of day.

Accuracy limits

An estimate, not a tape measure.

Body-fat and waist figures are AI estimates, not medical measurements. Clothing, pose and light can shift the result from one week to the next.

Waist is the only circumference Pip shows. Pip doesn’t measure muscle, and there’s no BMI, visceral fat or metabolic age score.

Questions

Short answers about the waist estimate.

How close is the waist estimate to a tape measure?

Pip hasn’t published a comparison with tape-measure readings. Treat the figure as an estimate from photos, not a measurement, and look at the direction over several weeks rather than one number.

Can I enter my own tape measurements?

No. Pip doesn’t have a field for tape measurements. Waist is the only body measurement it shows, and it comes from your photos.

Does Pip measure hips or chest?

No. Waist is the only circumference Pip shows. It doesn’t show hip, chest or other sizes.
