About this app

Body Measurement & BMI Tracker has helped over 500,000 users achieve their weight and body fat goals.

The app allows you to track and chart all of your most important body measurements including weight, waist, hips, thighs, biceps, body fat percentage, and Body Mass Index (BMI). Don't keep your weight - Lose it!

In addition to being a weight loss tracker, this app allows you to track any custom body measurements you can think of (shoulders, skeletal muscle %, body water %, etc) on your mobile device. What’s more, you can instantly chart the changes in your body stats over time, and your data is automatically synced to the cloud if you log in.

GOOGLE HEALTH CONNECT

BMT syncs bidirectionally with Google Health Connect — your measurements flow automatically between apps, keeping your complete health picture in one place.

SIMPLE CALCULATIONS - CALORIE & BMI CALCULATOR

The app also includes a built-in body fat calculator and will calculate lean body mass, body fat mass, waist-to-hip ratio, BMI & daily caloric needs as well.

BODY FAT PERCENTAGE

When using a weight loss tracker, it is important to monitor not only what and how much you eat, but also your weight and other indicators of health such as body fat percentage, waist, hips, BMI, etc.

Since body weight can fluctuate up to 5 lbs (2.3kg) per day, it is important to weigh yourself on a regular basis and at a consistent time every day. This way, by looking at your body measurement chart, you will be able to assess your weight loss trend over time.

Some digital scales provide an estimate of body fat percentage, which you can save within Body Measurement Tracker to determine whether your weight loss is a result of a desirable loss in body fat. Alternatively, by measuring waist, neck, height, and hip circumferences the app’s body fat calculator will automatically calculate body fat and lean mass percentages and chart them over time.

If your lean body mass is calculated successfully, the app will also estimate your daily caloric need based on your stated activity level and sex.

MONITOR YOUR WEIGHT AND MEASURES

Body Measurement and Weight Loss Tracker is customizable allowing you to track anybody measurement you can think of and ignore the ones you are not interested in.

The following measurements are included by default:
📌 Waist
📌 Weight
📌 Hips
📌 Body Fat Percentage
📌 Body Mass Index (BMI)
📌 Chest
📌 Upper Arms (biceps and triceps)
📌 Lower Arms (forearms)
📌 Upper Legs (thighs/quads and hamstrings)
📌 Lower Legs (calves)
📌 Height

BODY PROGRESS PHOTOS

Keep tabs on how you look over time by taking an unlimited number of pictures of your body. Just like the rest of your data, your body progress photos are automatically synced so they can be viewed across devices, so you never have to worry about losing them ever again.

CALCULATED BODY STATS

The following body stats are automatically calculated if you have recorded the required measurements:
✔️ Body Mass Index (BMI) - This is the ratio of body mass to the square of the body height and is a very commonly used index to categorize a person as underweight, normal weight, overweight or obese. Overweight and obese individuals are at greater risk for coronary artery disease, hypertension, type 2 diabetes, stroke, and more.
✔️ Body Fat Percentage - This represents the total weight of fat divided by the total body weight. It can be estimated in many ways, but since the body fat calculator relies on the measurement of height, weight & body circumferences, the Navy Method for body fat estimation is used. This method relies on waist, neck & height measurements for males and waist, neck, height, and hip measurements for females.
✔️ Waist to Hips Ratio - The waist to hips ratio is a useful indicator of overall health.

Very easy to use, but use with caution if you don't want to pay for a subscription. I didn't realize this app doesn't back up your data without a subscription. One day, my phone completely died out of nowhere - completely bricked. I tried to get my data back on my new phone, but found out that data was now gone forever.

Thank you for this feedback. The application participates in Android Auto Backup, which if you have it setup, will automatically sync app data to Google Drive so it is available when reinstalling on a new device. If you had that setup and it did not work for you, please reach out to us directly so we can investigate.

I've been using this app for years but recent updates has made it completely unusable for someone using imperial units. Yes, you can set your preferred unit of measurement in the settings... but it doesn't work. Literally two seconds of QAing the change would have shown that. So my YEARS of measurements have been inflated to hell for no reason, making the data unusable and there's too much to fix.

I've been using this app for over a year to track my weight loss. It's very user friendly, organized, and really helps you monitor other areas if you also rely on stats and inches to keep track. I got a new phone yesterday and realized I was on a guest acct that never backed up on my phone. I made a login, but data didn't sync, so I reached out to the developer. He was so helpful, responsive, and got me up and running again. Best interaction with any app developer I've ever had!!!

What’s new

• Before & after – Compare two progress photos and share a before/after card. Free exports include a small watermark; Gold can share without it.
• Photos – Fullscreen photos show the whole image instead of cropping it.
• Measurements – If older entries were wrongly marked as custom, the app can detect and repair them so charts and filters work again.
• Stability – Fixes for crashes opening calculations and for age checks that could get stuck or block you incorrectly.
