Can I track body measurements in Apple Health?

Only some. Apple Health stores weight, height, BMI, body fat percentage, lean body mass, and waist circumference. It has no place for hips, chest, arms, or thighs, so you need another app for those.

How often should I measure my body?

Every one to two weeks is enough to see a trend. Measure at the same time of day, ideally in the morning before eating, so day-to-day swings don't hide real change.

Which body measurements should I track?

Waist, hips, chest, upper arms, and thighs cover most goals. If you're building muscle, track left and right sides separately, since they rarely change at the same rate.

Why do my measurements change when my weight doesn't?

Weight is a single total. If you lose fat and gain muscle at the same time, the scale can stay flat while your waist gets smaller, which is why many people track both.

The 4 Best Body Measurement Tracker Apps for iPhone in 2026

How to track waist, hips, chest, and arms on iPhone, which apps do it best in 2026, and how to measure so your progress is real.

Want to see your waist, hips, and arms change over time? Body Measurements Tracker is free to download.

Short answer

Apple Health is enough if you only track weight, body fat, and waist. For hips, chest, arms, and thighs you need a dedicated app. Progress is the pick for progress photos, and Body Measurements Tracker is the pick for charting many measurements side by side. Remeasure Body hasn't been updated since 2021.

The scale is one number, and it often sits still while your body changes. Lose a little fat and build a little muscle at the same time, and your weight can stay flat for weeks while your jeans fit differently. A tape measure catches that, as long as you write the numbers down somewhere you’ll actually look at them.

This post covers how to measure, what to track, and which iPhone apps are worth using. We make Body Measurements Tracker, one of the apps below, so we’ve tried to be clear about where the others do better.

How to measure your body accurately

Small differences in technique can look like progress, or hide it. A few habits keep your numbers comparable:

Measure at the same time of day, ideally in the morning before eating or drinking.
Use a soft tape measure, snug against the skin but not pressing in.
Find the same spot each time: your waist at the navel, your hips at the widest point, arms and thighs at a set distance from a joint.
Measure both sides of your arms and thighs if you’re building muscle.
Check every one to two weeks. Daily numbers bounce around, and the monthly trend is what counts.

What to track for your goal

Losing weight: waist, hips, and weight. The waist often moves first, even when the scale doesn’t.
Building muscle: chest, shoulders, upper arms, and thighs, with left and right tracked separately.
General fitness: waist, hips, chest, and body fat, plus anything that matters to you.

Apple Health: best if you only track weight and waist

The Health app is free and already on your iPhone. It stores weight, height, BMI, body fat percentage, lean body mass, and waist circumference, and shows each on a chart. It has nowhere to log hips, chest, arms, or thighs, which is where a dedicated app comes in.

Progress: best for progress photos

Progress, listed on the App Store as Body Measurements Tracker App, tracks weight, BMI, body fat, and common measurements, with Apple Health sync. Its strength is before-and-after photos you can compare side by side. If photos motivate you more than charts, choose this one.

Remeasure Body: a classic, now dated

Remeasure Body puts 28 measurements on a body outline and calculates ratios like waist-to-hip. The free version shows ads, Apple Health sync needs the paid upgrade, and its last App Store update was in March 2021.

Body Measurements Tracker: best for seeing every change

We built Body Measurements Tracker for people who track more than one or two numbers. It covers weight, waist, hips, chest, neck, shoulders, body fat, and more, with left and right arms, forearms, thighs, and calves kept separate. If something’s missing, you can add your own measurement with its own unit and color.

The idea was to see measurements together. You can plot weight and waist on one chart, for example, and save that comparison to check every few weeks. Entries sync with Apple Health in both directions and across your devices with iCloud, and you can export everything to a CSV file for a spreadsheet or a coach.

What it doesn’t do: progress photos, or camera-based body scanning. If those matter to you, Progress or a 3D scanning app is a better fit.
