What it is

The scale only tells half the story. We track the whole picture.

Weight alone is misleading. You can lose fat and gain muscle while the scale barely moves. FoodIdentifier tracks body fat percentage, lean muscle mass, and circumference measurements so you see real progress — even when weight stalls.

Weight + body fat %

Track weight and body fat percentage side by side. See whether you're losing fat or just water weight. Smart scales sync automatically.

5 circumference measurements

Waist, hip, chest, arm, and thigh measurements. The waist-to-hip ratio is a stronger predictor of health risk than BMI alone.

Progress photos timeline

Monthly photos in the same pose create a visual timeline. See changes the scale can't show — especially during body recomposition.

How it works

Four steps to track what actually matters

No special equipment required. Use any scale and measuring tape. Smart scales sync automatically if you have one.

1

Log your weight

Step on any scale and enter your weight. Or connect a smart scale via Apple Health for automatic sync. Weekly is ideal.

2

Measure circumferences

Use a measuring tape for waist, hip, chest, arm, and thigh. Takes 2 minutes every 2 weeks. FoodIdentifier sends reminders.

3

Take a progress photo

Same pose, same lighting, once a month. FoodIdentifier builds a side-by-side timeline automatically.

4

Watch the trends

Visual charts show body fat % declining, muscle mass increasing, and waist shrinking — even when weight barely changes.

What you track

Six metrics that reveal your true progress

Stop obsessing over the scale. These six metrics tell you whether your body is actually changing.

Weight

Weekly tracking with trend line that smooths daily fluctuations. See your real direction, not water noise.

Body fat percentage

The #1 health metric. Track fat loss specifically — not just weight loss. Syncs from smart scales automatically.

Lean muscle mass

Track muscle gain during recomposition. If weight is stable but muscle is up and fat is down, you're winning.

Waist circumference

Waist measurement is a stronger predictor of cardiovascular risk than BMI. Track it every 2 weeks.

Waist-to-hip ratio

Automatically calculated. Below 0.9 (men) or 0.85 (women) means low metabolic risk. Track your progress toward it.

Progress photos

Monthly visual timeline. The most motivating metric — see changes the numbers can't capture.

Common questions

FAQ

What body composition metrics does FoodIdentifier track?
Weight, body fat percentage, lean muscle mass, waist/hip/chest/arm/thigh circumference, BMI, and progress photos — all tracked over time with visual charts.
Do I need a smart scale?
No. You can manually enter weight and measurements from any scale and tape. If you have a smart scale (Withings, Renpho, Eufy), body fat and muscle mass sync automatically via Apple Health.
Why is body composition better than just weight?
Weight hides progress. You can lose 5 lbs of fat and gain 3 lbs of muscle — the scale shows 2 lbs change, but your body transformed. Body composition shows the real story.
How often should I log measurements?
Weight: weekly. Circumferences: every 2 weeks. Progress photos: monthly. FoodIdentifier sends smart reminders and charts your trends automatically.
Can I track progress photos?
Yes. Take a monthly photo in the same pose and lighting. FoodIdentifier creates a side-by-side timeline so you can see visual changes the scale cannot capture.
