About this app

BodyGap turns your measurements into a body you can actually see — and shows the gap between where you are and where you want to be.

Most fitness trackers stop at numbers and line charts. BodyGap draws your current silhouette against a "ghost" of your ideal, so the gap is obvious and closing it becomes the goal you can watch every week.

THE SCALE STOPS MOVING. YOUR BODY DOESN'T.

Every cut and every bulk hits a stretch where the scale sits still. When you're gaining muscle and losing fat at the same time, weight barely changes — and that's exactly when most people decide it isn't working and quit.

Two centimeters off your waist means your body changed, whatever the scale says. BodyGap tracks body parts instead of bodyweight, so the plateau that looks like failure shows up as what it actually is: progress.

NO PHOTOS, NO SCANNING
BodyGap uses manual input only. There's no camera, no AI photo estimation, and none of the lighting, posture or body-type bias that comes with body scanning. Enter a few numbers once a week and you're done in two minutes.

PRIVATE BY DESIGN
Your body is sensitive data. BodyGap keeps every measurement on your device — nothing is uploaded, no account required, nobody else ever sees it.

WHAT YOU CAN DO
• Visualize arm, chest, waist and thigh against your target silhouette
• Switch between front and side views, female and male base shapes
• Log weekly and track each body part on its own chart
• See a 30-day projection of your progress at your current pace
• Start fast with goal-shape presets
• Set a reminder so you don't skip a week
• Share your progress card

SEE NEXT MONTH BEFORE IT ARRIVES
BodyGap works out how fast each measurement is moving and projects where you land in 30 days at this pace. Seeing "here's where this month ends up" changes what today's training and today's meals are worth. And if the pace isn't enough, you find out now instead of a month from now.

WHO IT'S FOR
• Anyone cutting who needs proof during a scale plateau
• Lifters bulking who want to confirm the right parts are growing
• People in a deficit checking they aren't losing what they wanted to keep
• Physique and contest prep
• Anyone working toward a smaller waist or more defined shape
• Postpartum body recomposition
• New gym members who quit before results show
• Anyone outgrowing a spreadsheet full of tape measurements

HOW TO MEASURE WELL
Consistency beats precision. Pick a day and a time (after waking, before eating is the most stable), use the same tape, and hold the same posture. Day-to-day numbers swing about a centimeter on water weight alone — that's why BodyGap charts by week. Read the slope of the line, not yesterday's reading.

FREQUENTLY ASKED QUESTIONS

Q. Can I log bodyweight too?
A. Yes, but measurements are the point. Catching progress while the scale is frozen is the whole reason this app exists.

Q. How often should I measure?
A. Once a week. Daily measuring buries the signal in water-weight noise and gets abandoned within a month.

Q. Does my data sync anywhere?
A. No. Everything stays on your device and is never sent to a server.

Q. Does it work for men?
A. Yes. Male and female base shapes are both included and switchable, and it handles bulking as well as cutting.
